The aim of this study was to evaluate the clinical remodeling of the alveolar socket following the application of bovine-derived xenograft collagen and collagen membrane compared to natural spontaneous healing during the first 6 months following tooth extraction. A total of 20 patients with 20 fresh alveolar sockets were randomly allocated into a test or control group. After a 6-month follow-up period, surgical reentry was performed and implants were placed. Significant statistical differences were recorded in terms of vertical and horizontal bone changes between the test and control groups...

Regenerative therapies are commonly needed prior to implant placement in the posterior maxilla following tooth extraction. The aim of this study was to investigate the anatomical features of the atrophic posterior maxilla that might affect surgical approach selection and technique and risk of intra- and postoperative complications. Cone beam computed tomography files were screened to identify pristine atrophic maxillary ridges in need of bone augmentation (ridge height < 10 mm). Ridge height and width and lateral wall thickness (LWT) were measured at different levels, and palatonasal recess and lateral wall morphology were calculated...

This study was conducted to evaluate the effects of platelet-rich fibrin (PRF) on palatal wound healing after free gingival graft (FGG) harvesting. A total of 125 patients were randomized after FGG: PRF with butyl-cyanoacrylate (BC) adhesive (PRF group; n = 42), BC adhesive alone (BC group; n = 42), and sterile wet gauze compression (WG group; n = 41). Bleeding, pain, epithelialization, feeding habits, and sensation scores were recorded for different time points. Statistically significant differences were found for all parameters in favor of the PRF group (P = ...

Histologic and histomorphometric evaluations of gingival biopsy samples of patients presenting either a thick or a thin gingival biotype were performed. Full-thickness gingival biopsy samples were obtained and processed for histologic and histometric evaluations. Thickness of the keratinized mucosa or gingiva was found to be increased in the thick biotype. Specifically, the connective tissue layer was thicker with no change in epithelial thickness. In conclusion, gingival transparency appears to be an adequate, clinically useful method to classify the gingival biotype...

Stavros Pelekanos, Georgia Pozidi
Reductions in peri-implant bone height have been acknowledged as a normal consequence of implant therapy. Various restorative factors contribute to this phenomenon. One is repeated abutment retightening, which causes a mechanical disruption at the implant-abutment interface, leading to soft tissue recession. Several investigators proposed placement of the definitive abutment after implant placement as a solution to the problem. The definitive use of an intermediate abutment after implant placement seems to positively affect the soft tissue response...

In this 3-year follow-up study, peri-implant bone loss at bone-level implants was evaluated with two definitive abutment heights: 1 mm and 2.5 mm. Peri-implant bone loss was defined as the distance between the implant shoulder and the first bone-to-implant contact from the time of loading to the 36-month follow-up, estimated using periapical radiographs. The bone loss was increased at the time of follow-up, to 1.30 mm (95% confidence interval [CI]: 0.70-1.89 mm; SD = 1.89) and 0.33 mm (95% CI: 0.11-0.55; SD = 0...

The aim of this study was to describe a protocol and analyze the outcomes of immediate replacement of failed implants due to peri-implantitis. A total of 17 patients (mean age: 58 ± 10 years) had 22 failed implants that were immediately replaced. One implant failed 16 months after insertion, resulting in an implant survival rate of 94.7%. The mean follow-up time was 40 ± 16 months (range: 9-52 months) after insertion. Mesial and distal bone loss were 0.89 ± 0.62 mm and 0.97 ± 0.66 mm, respectively. Immediate implant replacement could be considered in the management of implant failure due to peri-implantitis...

The purpose of this study was to compare microcomputed tomography (microCT) and histologic analysis outcomes of a periodontal regeneration of a human defect treated with a polylactic- and polyglycolic-acid copolymer. At 11 months following the grafting procedure, the root with the surrounding periodontal tissues was removed and analyzed using microCT and histologic techniques. The results suggest that microCT three-dimensional analysis may be used in synergy with two-dimensional histologic sections to provide additional information for studying the regeneration outcomes normally reported by histologic biopsies in humans...

This study investigated the dimensional change and microstructure of intraoral bone block grafts covered with platelet-rich fibrin (PRF) and a barrier membrane in ridge augmentation. Seven patients were included, with 18 implant sites (10 ramus and 8 symphysis). The average final ridge width gains in the ramus from cast-based measurement (3.86 ± 0.87 mm) and cone beam computed tomography measurements (3.63 ± 1.38 mm) were not different from the symphysis (3.36 ± 2.26 mm and 3.44 ± 1.52 mm, respectively)...

The present case report describes a modification of the connective tissue graft wall technique with enamel matrix derivative applied to treat deep vertical bony defects. The technique presented uses a palatal incision to gain access to the bony defect. Deep infrabony defects affecting two maxillary central incisors associated with interdental and buccal gingival recession were treated. At 1 year after surgery, 9 and 6 mm of interdental clinical attachment level gain were seen in cases 1 and 2, respectively...

The goal of this article is to demonstrate the practicality and results of increasing the zone of keratinized tissue on the lingual surface of mandibular anterior teeth via case reports. Calculus is most commonly found on the lingual surface of these teeth, so they are subjected to inflammatory elements resulting in tissue deformation and destruction. Significant attention has been paid to grafting the buccal surface, but there is a paucity of information addressing the lingual surface of mandibular anterior teeth...

The aim of this study was to histologically examine any epithelial cell inclusions in submerged subepithelial connective tissue graft (SCTG) after clinical healing was achieved. A total of 16 patients with Miller Class I or II gingival recessions were consecutively treated with a bilaminar procedure. At 2 months after surgery, a gingival tissue specimen was harvested from all SCTG-treated sites and stained with hematoxylin-eosin. The histologic evaluation revealed connective tissue in active reorganization without epithelial inclusions in 14 of the 16 tissue specimens...

The clinical effects of treatment with 808- and 980-nm diode lasers as an adjunct to a uniform and consistent nonsurgical periodontal treatment protocol (NSPTP) for initial probing pockets ≥ 6 mm with a 10-year follow-up were evaluated. In total, 24 patients (16 test cases and 8 control cases) were treated with the NSPTP. The control group (CG) was treated only with nonsurgical conventional therapy, while the test group (TG) received treatment with thermal diode lasers (wavelength of 808 or 980 nm). All patients had recall visits every 3 months and were reevaluated at 1 year after NSPTP...

Guided bone regeneration has become more predictable due to advances in material sciences. Nevertheless, vertical ridge augmentation (VRA) remains a potential challenge due to the complexity of soft tissue management. This becomes more complicated in the posterior atrophic mandible due to limited access and poorer blood supply. As such, a number of critical elements must be taken into consideration in treatment planning. Anatomical structures potentially jeopardize intraoperative adverse events such as bleeding or neurosensory disturbances...

This retrospective study reports on the outcome of 19 narrow-diameter implants (NDIs) placed in 14 consecutively treated patients 3 to 14 years postloading. Peri-implant bone remodeling, bone loss, esthetic outcomes, and patient satisfaction with the final restoration were evaluated. No implant failures or prosthetic complications were reported, yielding a 100% survival rate and a 84.2% success rate. All 14 patients reported that they were very satisfied with the esthetic results. The average mesial and distal bone remodeling was 1...
