Abstract Background The primary stability in immediate implant placement was considered one of the prerequisites for the achievement of good osseointgration. The insertion torque varies between cases depending on many factors and may goes down to Zero that may affect the prognosis of the implant especially in the soft maxillary bone. The aim of the study was to assess clinically the success&/or failure of immediate flapless implant placement in the maxilla with Zero insertion torque measurement with a follow up time ranging 2-4 years. Results: out of 780 analyzed, fourteen implants were placed in fresh extraction sockets for single rooted teeth in the maxilla and did not get primary stability (zero insertion torque). Their survival rate was 85.7%. Conclusions: The loss of torque during immediate implant placement to Zero may jeopardize the survival of the implants, but it may not be statistically significant with their failure and loss. The lack of certain conditions that are absent during their surgical installation and healing have the major effects on success. The implant primary stability is not an absolute prerequisite to osseointegration; however, it may affect the implant survival rate. Key words: 0 torque implant insertion, implant primary stability, loose implant, immediate implant survival, immediate implant placement.

Molar Extraction

The ideal positioning of immediate implants in molar extraction sockets often requires the osteotomy to be in the interradicular septum, which can be challenging in some cases, with traditional site preparation techniques. Patients who had undergone molar tooth extraction and immediate implant placement at five different centers, and followed up between August 2015 and September 2020, were evaluated. Inclusion criteria were use of the osseodensification technique for implant site preparation. The primary outcome was septum width measurement pre-instrumentation and osteotomy diameter post expansion. Clinical outcomes, such as implant insertion torque (ISQ) and implant survival rate, were also collected. A total of 131 patients, who received 145 immediate implants, were included. The mean overall septum width at baseline was 3.3 mm and the mean osteotomy diameter post instrumentation was 4.65 mm. A total of ten implants failed: seven within the healing period and three after loading; resulting in a cumulative implant survival rate of 93.1%. This retrospective study showed that osseodensification is a predictable method for immediate implant placement with interradicular septum expansion in molar extraction sockets. Furthermore, it allowed the introduction of a new molar socket classification. In the future, well-designed controlled clinical studies are needed to confirm these results and further explore the potential advantages of this technique.

Molar Extraction

The placement of immediate implants in the posterior sector is a widespread procedure where the success and survival rates are similar to those of traditional protocols. It has several anatomical challenges, such as the presence of interradicular bone septa that hinder a correct three-dimensional positioning of the implant and may compromise primary stability and/or cause damage of neighboring structures. The aim of this article is to present the treatment and the one-year clinical follow-up of a patient who received immediate implant placement using an interradicular bone-drilling technique before the molar extraction.

Narrow Diameter Implants

Narrow-diameter implants (NDIs) are increasingly produced and used in implant dentistry, especially since the introduction of new, more resistant materials. The objective of the present study was to evaluate the clinical performance of NDIs (3.3 mm) placed in thin alveolar crests. Twenty consecutive patients needing implant-supported fixed partial dentures and presenting an alveolar thickness ≤6 mm were treated with 1 or several NDIs. The surgical protocol was chosen according to the clinical situation: (1) flapless, (2) mini-cervical flap, (3) wide flap, (4) wide flap + guided bone regeneration (GBR). Implants were immediately loaded if the primary stability was higher than 20 Ncm. Implant survival and success, prosthodontic success rates, and patient-centered outcomes were evaluated after a follow-up period of 1 year. A total of 39 implants were placed in 20 patients, 12 and 27 implants in the anterior regions and in the posterior mandible, respectively. All but 1 implant reached an insertion torque higher than 20 Ncm and were loaded within 48 hours. The implant survival and success rates both reached 94.7%. The need for GBR was avoided in 60% of the implant sites. The mean peri-implant bone remodeling after a follow-up period of 1 year was −0.35 mm at the implant level. Peri-implant bone remodeling was higher in the posterior region, when the alveolar crest was thinner than 4 mm and GBR was required in addition. In conclusion, use of NDIs to restore partial edentation in sites with limited horizontal thickness seems to be an effective treatment option that prevented GBR in the majority of the present cases. Immediate provisionalization of NDIs does not seem to impair the results.

Objective: The purpose of this study was to evaluate the survival rate and the amount of periimplant bone loss in implants placed in free iliac graft following segmental mandible resection. Materials and Methods: Over a 5-year period between 2010 and 2015, nine patients with odontogenic tumors who were candidate for segmental mandible resection were enrolled in this study. Resection defect was immediately reconstructed with non-vascularized iliac graft and 4-6 months later 36 implants of 5 different brands were inserted in grafted mandibles. Information regarding implant survival, peri implant bone loss or inflammation for a mean follow up period of 33 months was obtained. Results: One implant was failed out of 36 implants and the cumulative survival rate of implants was 97.2% in this follow up period. There was no sign of peri implant inflammation or gingival recession or BOP in any patients. The cervical bone loss level varied between 0.6 to 12mm (the length of failed implant) with the average of 0.96 mm. The bone loss level of survived implants varied between 0.6to 1.72mm with average of 0.64mm. Conclusion: This study demonstrated that reconstruction of segmental mandibular defect with non vascularized iliac graft followed by dental implant placement is an effective and predictable method to restore oral function.

Preliminary Study

Abstract The purpose of this study was to observe the clinical outcome of bone spreading and standardized dilation of horizontally resorbed bone during immediate implant placement using a “screw-type” configuration of expansion and threadformers. Fifty-three patients were included in this study, and 41 edentulous areas in anterior and posterior maxillas were treated. Sixty-eight implants were placed using an insertion torque of at least 40 Ncm. Abutments were delivered 4 to 6 months after implant placement. The overall failure percentage was 4.41% (3 failures). A retrieved analysis of 1 implant removed at 3 years after placement demonstrated bone resorption down to the level of the third thread. The bone spreader technique is different from Summers' osteotome, both in clinical use and in armamentarium. The main advantage of the crest-expanding technique is that it is a less invasive procedure; the facial wall expands after the medullary bone is compressed against the cortical wall. Within the limits of this preliminary study, the cumulative survival rate for this method of implant placement is 95.58% at 3 years. This study confirms that a bone spreader used in the maxilla shows an unusually low failure rate after 3 years.

The purpose of this study was to evaluate the survival rate and incidence of prosthetic complications in 377 implants with a double octagon connection. Furthermore, the correlations among implant dimensions (diameter and length), bone quality, and insertion torque were investigated. A 4-year multicenter prospective clinical study was designed to evaluate the survival rate of 377 dental implants inserted in 189 patients between January 2004 and April 2010. After an average follow-up of 46 months, the implant survival rate was 99.7%, and the incidence of complication was 0.53%. Moreover, insertion torque was statistically related in a significant way to implant diameter. The connection system seemed to reduce the risk that the prosthetic component screw would loosen. Within the limits of this study, it was observed that a wider diameter corresponded to a higher implant primary stability. Implant length did not seem to be critical in obtaining higher primary stability.

Abstract Objective The purpose of the present prospective, case-series study was to report implant survival rate and marginal bone remodeling expected 5 years after loading using dental implants placed in daily practice. Materials and Methods This research was designed as an open-cohort, prospective, case-series evaluation. Any partially or completely edentulous patient, scheduled to receive at least one bone level implant, was considered eligible for this study. Primary outcome measurements were: implant and prosthetic cumulative survival rate and any complications experienced up to the 5-year follow-up. Secondary outcome measures were: thickness of gingival biotype, implant insertion torque, implant stability quotient, and marginal bone loss (MBL). Results Ninety consecutive patients (34 males and 56 females, aged between 24 and 81 years old [mean: 53.2 ± 15.4]) with 243 inserted implants were followed for at least 5 years after loading (mean: 65.4 ± 3.1 months; range from 60 to 72). At the 1-year follow-up, no drop-outs were recorded, but 17 patients (18.9%) with 18 restorations (12.6%) delivered on 34 implants (14%) were lost at the 5-year examination. At the 5-year follow-up examination, six implants lost osseointegration (97.5%). In the same period, four prostheses failed (97.2%). Five complications were reported in five different patients (prosthetic success rate was 96.5%, at patient level). Five years after loading, the mean MBL was 0.41 ± 0.30 mm. The difference from the 1-year data was 0.04 ± 0.19 mm. A statistically significant higher MBL was found for smokers, and patients with thin gingival biotype. The mean implant insertion torque was 42.9 ± 4.8 Ncm (range from 15 to 45 Ncm). Two-hundred and three implants (83.5%) were inserted with an insertion torque ≥35 and ≤45 Ncm. Conclusions High implant survival and success rate could be expected with stable marginal bone remodeling up to 5 years after loading. Smoking and thin tissue biotype were the most important variabilities associated with higher MBL. Further research studies are needed to confirm these results.

Since the presence of keratinized gingiva is so important for peri-implant outcome, the aim of this study is to describe a partial thickness flap design to increase the amount of keratinized peri-implant tissue as well as its thickness. A total of 131 implants were placed in 85 patients: 103 implants (78.63%) in the mandible and 28 implants (21.37%) in the maxilla. Before implant placement in edentulous ridge the residual keratinized mucosa usually was measured with a periodontal probe in a buccal–palatal direction. A palatal or lingual incision was made to raise a partial thickness flap with the residual keratinized tissue. After implant placement the flap was apically repositioned and secured with loose periosteal sutures. Keratinized tissue levels were calculated at baseline, at 6 months, and every year follow-up. Measurements were reported for each implant diameter. At 4-year follow-up, implant survival rate of 87.79% was reported. Peri-implant keratinized mucosa confirmed clinical gain in all cases; mean levels at 1- and 4-year follow-ups were 7.26 ± 2.01 mm and 7.37 ± 2.12 mm, respectively. The levels remained stable over time. This flap design allows immediate correction of adaptation of the keratinized tissue around the implant, increasing the thickness and amount of the keratinized tissue.
