Background: To assess the clinical and histomorphometric data of the new bone tissue from a mixture of autologous bone and β-tricalcium phosphate. Materials and methods: A total of 72 two-stage sinus lift were performed in 54 patients during 2007 to 2010. The autologous bone was harvested from the mandibular ramus and mixed with the β-tricalcium phosphate Poresorb® TCP sized 1-2 mm. The materials were used in a proportion ranged between 1:1 and 1:3. After the healing period a total of 119 implants were placed and 10 samples of the regenerated bone were collected for the histomorphometric analysis. CBCT or panoramic X-rays were performed presurgically, before the implant placement, six months after implant placement and then yearly to evaluate the bone formation and marginal bone loss. The implant success rate was determined using the Albrektsson et al. Criteria. Results: The mean of the residual bone was 4.07 mm ± 1.87 mm. The bone gain in the sinus was 11.91 mm ± 2.80 mm. The implant success rate was 94.95%. The histomorphometric measurements on the biopsies showed a bone area mean of 39.7 ± 9.71%. The residual allograft area was 16.21 ± 8.78%. The connective tissue was 44.16 ± 5.85%. Conclusion: Within the limit of this study, the osteoconductive β-tricalcium phosphate associated with autologous bone is a viable grafting material for sinus lift procedures. The use of composite grafts can help to reduce the morbidity and aggressivity of the bone harvesting.

Objectives: The objective of this cross-sectional study was to evaluate the vertical bone gain achieved after the sinus lift procedure with beta-tricalcium phosphate (β-TCP) used as a bone substitute and simultaneous implant placement. Methods: One hundred and twenty-eight sinus lift procedures (utilizing a synthetic ceramic containing 99.9% tricalcium phosphate as a bone substitute) and simultaneous implant placements were performed on 119 patients. The lateral window approach surgical protocol for maxillary sinus lift was performed on the patients. The implants were evaluated using cone-beam computed tomography (CBCT) at 6 months following placement. The vertical bone gain was considered a primary variable, while implant length, diameter, and location were considered secondary variables. Results: The ANOVA results showed no statistical difference in vertical bone gain with implant parameters like implant length, width, and position. Pearsons correlation revealed a statistically significant positive correlation with vertical bone gain and implant length and diameter. A further multivariate linear regression analysis was performed and it observed statistically significant associations between the variables in the study after adjusting for confounding factors. Conclusions: This study concluded that there was vertical bone gain with the usage of β-TCP in maxillary sinus lift surgical procedure with immediate implant placement and that implant variables like length and diameter had a significant influence on the average bone gain values. The implant position did not have a statistically significant influence but there was considerable variation in the bone gain between first, second premolar, and molar regions.

Abstract Endosseous implants are the treatment of choice for restoring function and reconstructing most edentulous areas of the maxilla and mandible. In general, alveolar bone defects can be reconstructed by either distraction osteogenesis or autogenous bone grafting. After alveolar reconstruction, endosseous implants are used to support and retain the prosthesis for restoration of form and function. Eighty-two consecutive patients requiring alveolar augmentation prior to implant placement were evaluated. All patients were given treatment options for reconstructing their alveolar defects, which included autogenous bone grafting vs distraction osteogenesis. Sixty-five patients received autogenous grafts (anterior iliac crest: 44; retromolar: 17; tibia: 2; chin: 2), and 17 patients underwent distraction osteogenesis prior to implant placement. A total of 184 implants were placed in the autogenous bone-grafted sites and 56 implants in the distracted bone sites. Implants placed in sites restored with autogenous bone grafts had an implant success rate of 97% (178/184), whereas implants placed in distracted bone sites had a success rate of 98% (55/56). In the autogenous grafted group, 3 implants failed in the posterior mandible, one in the anterior maxilla, one in the anterior mandible, and one in the posterior maxilla. In the distraction group, one implant failed in the posterior mandible. Both techniques are associated with good success rates. There was no statistical difference between implant success in autogenous bone vs distracted bone sites in this group of patients.

The aim of this retrospective study was to clinically evaluate the five-year outcomes of implants placed following a combined approach to the sinus, consisting of sequential drills and osteotomes. Medical records of patients with implants placed in combination with crestal sinus lift using sequential drills and osteotomes, with a residual alveolar bone crest between 4 to 8 mm, and a follow-up of at least five years after final loading, were evaluated. Outcomes were implant and prosthetic survival and success rates, any complication, and marginal bone loss. Data from 96 patients (53 women and 43 men; mean age 54.7 years; range 23–79 years) were collected. A total of 105 single implants were analyzed. After five years of function, two implants were lost and two prostheses failed. No major biological or prosthetic complications occurred. At the five-year examination, the marginal bone loss was 1.24 ± 0.28 mm. Within the limitations of this retrospective study it can be concluded that implants placed following a combined approach to the sinus consisting of sequential drills and osteotomes seem to be a viable option for the treatment of posterior atrophic edentulous maxilla.

Autologous Bone

Introduction:Autologous bone is considered to be the “gold standard” for the reconstruction of the reabsorbed alveolar ridges. For small defects, autologous bone samples can be harvested from intraoral donor sites. However, extraoral donor sites are the first choice for any extensive augmentation of the alveolar ridges. The resorption of the bone grafts depends on several factors, including the recipient sites, the donor sites, volume of the bone grafts and whether or not the patient smokes. The aim of this study was to investigate the rate of autologous bone graft resorption, 4 months after the surgical reconstruction, according to their sites of origin, parietal or ramus, according to the grafted site, mandible or maxilla and according to the surgical indications.Patients and methods:22 patients had 51 reconstructions of alveolar ridges with ramic or parietal onlay bone grafts. The increase of bone volume was assessed with computed tomography, immediately after augmentation (V0) and 4 months after the procedure (V1), before the placement of dental implants.Results:The mean rate of bone resorption was 26% for the parietal bone grafts and 27% for the ramus bone grafts after 4 months (p: ns). This rate was 26% for maxillary grafts and 25% for mandibular grafts (p: ns). This rate varies from 22% to 33% according to the etiology of the bone defect but these variations are not significant and ultimately, this rate of bone resorption was unaffected by the gender of patients.Conclusion:Based on these findings, the resorption of onlay grafts doesnʼt seems to be affected by the recipient and donor sites nor by the etiology of the bone defects. Parietal and ramic bone grafts showed limited resorption rates for the pre-implant reconstruction of alveolar ridges.

Abstract In the past decade, several investigators have reported that implants inserted in autografts in the same operation (ie, simultaneously inserted implants [SIIs]) have achieved excellent results. However, no report regarding SIIs placed in fresh frozen bone (FFB) is available. Thus, the authors planned a retrospective study on a series of SIIs placed in homologue FFB (but not immediately loaded) to evaluate their clinical outcome. In addition, a comparison with implants inserted in FFB in a second stage (ie, delayed inserted implants) was performed. Seventeen patients were grafted with FFB, and 48 implants were inserted in the same operation. Implant diameter and length ranged from 3.25 to 4.0 mm and from 10.0 to 15 mm, respectively. Data were compared with 302 implants inserted in FFB in a second operation during the same period in 64 patients. Analyzing SIIs, it was noted that only 3 implants were lost (ie, survival rate [SVR]  =  93.7%), and no differences were detected among the studied variables by using lost implants as a predictor of clinical outcome. On the contrary, by using crestal bone resorption around the implant's neck and specific cutoff values, it was possible to demonstrate that prosthetic restoration (ie, removable overdentures) correlated with a statistically significant lower delta insertion abutment junction (ie, reduced crestal bone loss) and thus with a better clinical outcome. By comparing SIIs with implants inserted in a second stage in FFB, a better outcome for delayed implants was demonstrated. Implants inserted simultaneously with FFB grafts had a high survival and success rate. SIIs inserted in FFB can be considered reliable devices, although a higher marginal bone loss is to be expected when fixed prosthetic restorations are used. Implants inserted in a second surgical stage have a better SVR and success rate than SIIs.

Sinus Grafting

For sinus grafting, the authors propose a minimal posterior iliac bone harvesting, with local anesthesia. Autogenous bone grafting continues to be considered the gold standard for sinus grafting. The classic harvesting sites are calvarial, anterior iliac, and tibial, and harvesting is usually practiced under general anesthesia. We performed this technique in 7 patients under local anesthesia. In the posterior iliac crest, with a specific trocar for bone puncture biopsy, bone was harvested. We performed 1 cm longer for 5-mm diameter of bone. Three bone biopsies were harvested on each side. The harvested cancellous bone (5 cm3) was mixed with triphosphocalcic (TCP) material (2 cm3), and blood (1 cm3). A classic sinus lift was realized. After 6 months, the success rate of bone grafting was 100%. Each of the 7 patients could be implanted by an average of 4 dental implants by superior maxillary. For sinus lift, this simple posterior iliac-bone biopsy harvesting under local anesthesia is very comfortable for the patient and also safe. It provides enough marrow bone to be mixed with TCP for a sinus lift.

Long Term Studies

Background. Long-term edentulism may in many cases result in resorption of the alveolar process. The sinus lift procedure aims to create increased bone volume in the maxillary sinus in order to enable installation of dental implants in the region. The method is over 30 years old, and initially autogenous bone grafts were used and later also different bone substitutes. Since 1997, a limited number of studies have explored the possibility of a graftless procedure where the void under the sinus membrane is filled with a blood clot that enables bone formation.Aim. To describe the evolution of the sinus-lift technique and to review the literature related to the technique with a focus on long-term studies related to the graft-less technique.Methods. The electronic database PubMed was searched, and a systematic review was conducted regarding relevant articles.Results. A relatively few long-term studies using the described technique were found. However, the technique was described as reliable considering the outcome of the existing studies.Conclusion. All investigated studies show high implant survival rates for the graftless technique. The technique is considered to be cost-effective, less time-consuming, and related to lower morbidity since no bone harvesting is needed.

Background: Sinus grafting with autogenous bone and other bone substitutes has been shown to be a safe technique with high predictability of success, but it has not been determined which of these materials provide better osteogenic potential. The aim of the present study was to clinically and radiographically evaluate the use of Natix™ grafting material in maxillary sinus elevation procedures with simultaneous implant placement in humans. Materials and Methods: Fifteen patients (6 women and 9 men) requiring augmentation of the maxillary sinus before implant placement were voluntarily enrolled in this study. After the sinus graft procedure, a bone augmentation material of porous titanium granules (Natix™, TigranTecnologies, Malmö, Sweden) was placed into the sinus cavity. The primary stability of the fixtures was measured at baseline and 6 months following the implantation. Panoramic x-rays for objective measurements of bone height at the floor of sinus were repeated at 18 months, and 36 months postoperatively. Results: The 15 patients had in total 20 implants installed. Panoramic radiographs made 6 months post-insertion showed a radio-opaque area around the implants.Also at 6 months post-placement, all 18 implants were clinically stable and abutments were connected. Bone biopsies were taken from 1 grafted site in 1 patient. Excluding the one implant failing to achieve primary stability at baseline, the cumulative implant survival rate in this pilot study was 94.7%. Conclusion: The results of the study showed that maxillary sinus augmentation with porous titanium granules provided predictable survival of implants in 36 months.

Background: The aim of the present prospective case series study was to evaluate the implant and prosthetic survival rates, complications and marginal bone loss using ultra-fine titanium mesh membrane with simultaneous implant placement, to provide space maintenance mandatory for guided bone reconstruction of alveolar bone defects. Materials and Methods: patients were recruited and treated at a private clinic in Rome, Italy, between March 2016 and October 2017. Self-tapping tapered implants were placed through a computer-guided template-assisted approach. Autogenous bone was placed alone over the exposed implant surface, then mixed with inorganic bovine bone material. Finally, the membrane was connected and shaped in order to securely enclose the graft area, and the healing cap was connected and screwed onto the height connector. Outcome measures were: implant and prosthetic failure, biological and mechanical complications, marginal and volumetric bone level changes, esthetic evaluation performed according to the pink aesthetic score (PES). Results: in total, seven patients (five women, two men) with a mean age of 52.7 ± 20.3 years (range: 27–71) received 10 self-tapping tapered implants and simultaneous guided bone regeneration with ultra-fine titanium mesh membranes. No implants and no prostheses failed during the entire follow-up period. One slightly membrane exposure was observed one month after implant placement in one patient. The mean marginal bone loss (MBL) at implant loading was 0.13 ± 0.09 mm (95% CI 0.08–0.19). At the 18-month follow-up examination, the mean MBL was 0.28 ± 0.33 mm (95% CI 0.07–0.50) The difference was not statistically significant (0.15 ± 0.31; 95% CI 0.05–0.35; P = 0.1888). The mean horizontal alveolar ridge width was 3.72 ± 1.08 mm (95% CI 3.22–4.22 mm). At the II-stage surgery, the mean bone width was 8.79 ± 0.98 mm (95% CI 8.51–9.07 mm). The mean bone gain was 5.06 ± 1.13 mm (95% CI 4.68–5.44 mm; P = 0.000). The mean volume of the grafted bone calculated using the superimposition technique was 0.99 ± 0.38 CC (95% CI 0.75–1.23 CC). The mean PES at implant loading was 8.2 ± 0.8 mm (95% CI 7.7–8.7). At the 18-month follow-up examination, the mean PES was 12.0 ± 0.7 mm (95% CI 11.5–12.5) The difference was statistically significant (3.8 ± 0.4; 95% CI 3.5–4.1; P = 0.0000); Conclusion: with the limitation of the present prospective study, the guided bone reconstruction using an ultra-fine titanium mesh membrane with simultaneous implant placement seems to provide good and stable results in implant/prosthesis success. Further research with a longer follow-up and a higher sample size are needed to confirm the results from this preliminary report.

Membrane pathology tends to complicate the postprocedural course of open sinus lift by ostio-meatal complex (OMC) obstruction and consequent acute sinusitis. The objective of this study was to evaluate the outcome of subjects with considerable sinus membrane pathology undergoing maxillary sinus floor augmentation and simultaneous implant placement using the minimal invasive antral membrane balloon elevation (MIAMBE) method. This study was a retrospective chart review of MIAMBE procedures performed in the presence of significant sinus membrane pathology. Sixteen patients with maxillary sinus membrane thickening in well-ventilated OMC as determined by dental computerized tomography underwent sinus augmentation and simultaneous implant placement using the MIAMBE technique. All 16 procedures were successfully concluded without significant procedural or postprocedural complications or implant failure. Post MIAMBE membrane pathology regressed or disappeared in 8 patients (50%) or remained unchanged in 6 patients (37.5%), while in 2 patients the sinus membrane pathology was limited to evaluation by periapical X rays. Sinus augmentation using the MIAMBE technique can be performed safely in asymptomatic patients in the presence of sinus membrane pathology if the OMC is not obstructed. In a significant proportion of these cases, complete resolution of the membrane pathology after MIAMBE is observed. When compared to open sinus lift, OMC obstruction is less likely to occur when employing the MIAMBE method.
