Bones and teeth are the only structureswithin the body where calciumandphosphate participate asfunctional pillars. Despite their mineralnature, both organs are vital and dynamic. The aim was to remark the indications for alveolar augmentation after tooth extraction and prior the placement of endoosseous dental implants. The autograft, allograft, alloplast, and xenograftmaterials all have reported success, alone or in combination,for particulate bone augmentation. Theparticulate autograft is the gold standard for mostcraniofacial bone grafting, including the treatmentof dental implant–related defects. Advantages of alveolar ridge augmentation with sufficient bone volume to adjust for uncompromised and esthetic implant placement, renders these procedures more than effective for majority of patients. Surgical reconstruction of the tissues and the procedure of ridge augmentation and subsequent placement of dental implant are necessary.

Ti Mesh

An adequate amount of bone all around the implant surface is essential in order to obtain long-term success of implant restoration. Several techniques have been described to augment alveolar bone volume in critical clinical situations, including guided bone regeneration, based on the use of barrier membranes to prevent ingrowth of the epithelial and gingival connective tissue cells. To achieve this goal, the use of barriers made of titanium micromesh has been advocated. A total of 13 patients were selected for alveolar ridge reconstruction treatment prior to implant placement. Each patient underwent a tridimensional bone augmentation by means of a Ti-mesh filled with intraoral autogenous bone mixed with deproteinized anorganic bovine bone in a 1:1 ratio. Implants were placed after a healing period of 6 months. Panoramic x-rays were performed after each surgical procedure and during the follow-up recalls. Software was used to measure the mesial and the distal peri-implant bone loss around each implant. The mean peri-implant bone loss was 1.743 mm on the mesial side and 1.913 mm on the distal side, from the top of the implant head to the first visible bone-implant contact, at a mean follow-up of 88 months. The use of Ti-mesh allows the regeneration of sufficient bone volume for ideal implant placement. The clinical advantages related to this technique include the possibility of correcting severe vertical atrophies associated with considerable reductions in width and the lack of major complications if soft-tissue dehiscence and mesh exposures do occur.

Abstract Background The purpose of this study was to evaluate the volumetric changes in partially edentulous alveolar ridges augmented with customized titanium ridge augmentation matrices (CTRAM), freeze-dried bone allograft, and a resorbable collagen membrane. Methods A pre-surgical cone beam computed tomography (CBCT) scan was obtained for CTRAM design/fabrication and to evaluate pre-surgical ridge dimensions. Ridge augmentation surgery using CTRAM, freeze-dried bone allograft, and a resorbable collagen membrane was performed at each deficient site. Clinical measurements of the area of augmentation were made at the time of CTRAM placement and re-entry, and a 2nd CBCT scan 7 months after graft placement was used for volumetric analysis. Locations of each CTRAM in situ were also compared to their planned positions. Re-entry surgery and implant placement was performed 8 months after CTRAM placement. Results Nine subjects were treated with CTRAM and freeze-dried bone allograft. Four out of the nine patients enrolled (44.4%) experienced premature CTRAM exposure during healing, and in two of these cases, CTRAM were removed early. Early exposure did not result in total graft failure in any case. Mean volumetric bone gain was 85.5 ± 30.9% of planned augmentation volume (61.3 ± 33.6% in subjects with premature CTRAM exposure vs. 104.9% for subjects without premature exposure, p = 0.03). Mean horizontal augmentation (measured clinically) was 3.02 mm, and vertical augmentation 2.86 mm. Mean surgical positional deviation of CTRAM from the planned location was 1.09 mm. Conclusion The use of CTRAM in conjunction with bone graft and a collagen membrane resulted in vertical and horizontal bone gain suitable for implant placement.

ABSTRACT Calcium sulfate is a biologically compatible osteoconductive graft material that binds underlying bone graft and provide space maintenance. The purpose of this study was to evaluate calcium sulfate as a barrier compared to a collagen membrane for augmentation of a standardized surgically created ridge defect. For this purpose, bilateral extraction of mandibular premolars was performed on six foxhounds (Canis familiaris). Eight weeks later, a standardized osseous ridge defects (24 total) were created using a 6 mm trephine. The study was approved by the Institutional Animal Care and Use Committee (IACUC) at Baylor College of Dentistry. The osseous defects were allocated into three groups (8 defects each): group 1 received autogenous bone graft covered with collagen membrane (CM); group 2 received autogenous bone graft covered with calcium sulfate barrier (CS), and group 3 was used as control and did not receive bone augmentation and was used as control. The animals were sacrificed after 12 weeks following bone augmentation and sites were evaluated histologically for total ridge width, percentage of bone gain and cortical bone thickness. Results All sites exhibited bony fill within the defect. Analysis of variance did not reveal statistically significant difference in the mean total bone gain among CM, CS, and control groups (12.2,11.6, and 11.9) mm2, respectively, p = 0.875. Conclusion Calcium sulfate does not appear to improve bone regeneration in an osseous defect. How to cite this article Heaton ML, Kerns DG, Hallmon WW, Kessler HP, Spears R, Solomon ES, Al-Hashimi I.

Background. Implant placement in defective anterior maxilla poses a great challenge regarding functional and aesthetic outcomes. Therefore, it requires predictable alveolar ridge augmentation. Deproteinized bovine bone mineral (DBBM) particle has commonly been used for bone grafting. However, it is associated with low resorption rates which potentially compromise the outcome of horizontal augmentation in conjunction with implant placement. Aims. This study is aimed at evaluating the stability of tissue augmented with DBBM particle associated with implant placement in the anterior maxilla. Materials and Methods. The inclusive criteria consist of patients being treated with guided bone regeneration (GBR) incorporating the use of DBBM particles with either a simultaneous or staged approach. The parameters analyzed include the implant survival rate, post-GBR clinical stability based on tissue resorption level, and the tissue stability between simultaneous and staged approaches. Statistical analysis using Mann-Whitney test is performed with significance determined at p value < 0.05. Results. Seventeen patients with 23 implant placements satisfy the criteria for this study. Simultaneous approach is adopted in 18 (78.3%) implants and a staged approach in 5 (21.7%) implants. The implant survival rate is 100%. The evaluation of horizontal tissue stability reveals a low resorption level in 19 (82.6%) implants, while moderate and high resorption levels are found in 3 (13.0%) and 1 (4.3%) implants, respectively. The statistical analysis shows that the simultaneous approach produces significantly (p=0.005) lower resorption level compared to the staged approach. Conclusion. Horizontal ridge augmentation using DBBM particles associated with implant placement in the anterior maxilla produces good clinical stability. The stability appears to be higher in the simultaneous approach compared to the staged approach.

Radiographic Presentation

Alveolar ridge deficiency is considered a major limitation for successful implant placement, as well as for the long-term success rate, especially in the anterior maxillary region. Various approaches have been developed to increase bone volume. Among those approaches, inlay and onlay grafts, alveolar ridge distraction, and guided bone regeneration have been suggested. The use of titanium mesh is a reliable method for ridge augmentation. We describe a patient who presented with a localized, combined, horizontal and vertical ridge defect in the anterior maxilla. The patient was treated using titanium mesh and alloplast material mixed with a nano-bone graft to treat the localized ridge deformity for future implant installation. The clinical and radiographic presentation, as well as relevant literature, are presented.

Autologous Bone

Autologous bone transfer is regarded as the gold standard for ridge augmentation before dental implantation, especially in severe bony defects caused by tumor resection or atrophy. In addition to the advantages of autologous bone, transplantation has several disadvantages, such as secondary operation, increased morbidity and pain. The present study reports, for the first time, a combination of a xenogeneic bone substitute (BO) with platelet-rich fibrin (PRF), which is a fully autologous blood concentrate derived from the patient's own peripheral blood by centrifugation. Solid A-PRF+ and liquid i-PRF together with an individualized 3-D planned titanium mesh were used for reconstruction of a severe tumor-related bony defect within the mandible of a former head and neck cancer patient. The BO enriched with regenerative components from PRF allowed the reconstruction of the mandibular resective defect under the 3-D mesh without autologous bone transplantation. Complete rehabilitation and restoration of the patient's oral function were achieved. Histological analysis of extracted bone biopsies confirmed that the new bone within the augmented region originated from the residual bone. Within the limitations of the presented case, the applied concept appears to be a promising approach to increase the regenerative capacity of a bone substitute material, as well as decrease the demand for autologous bone transplantation, even in cases in which autologous bone is considered the golden standard. PRF can be considered a reliable source for increasing the biological capacities of bone substitute materials.
