“…A very interesting study was conducted by Farias et al after obtaining a horizontal volume increase with the tenting screw technique in the posterior mandible using allogeneic material with blood products. The ISQ was measured to evaluate the primary and secondary stability of the implants [ 36 ].…”

The need to obtain adequate bone volumes for prosthetic rehabilitation supported by implants, using different techniques and materials, represents an urgent need in modern dentistry. We report a case regarding the management of implant-prosthetic rehabilitation of the first and second upper right molars, in which no less than 4 mm of crestal bone remained to insert two implants. Regeneration of the residual bone was previously performed using a customized titanium barrier and a filler of a blood clot with tricalcium beta phosphate. The bone gain (3 mm) was evaluated by comparing CBCT images, while the implant stability (mean 70) was assessed with the ISQ measurement. A regenerated bone sample was taken for histological analysis. Guided bone regeneration obtained with a titanium barrier and blood clot allowed for the insertion of stable implants in a mature bone without heterologous material.

“…The effect of GBR combined with titanium mesh for vertical bone augmentation is considerable, but the titanium mesh itself has the problem that the edge is easily exposed, which leads to failure of bone augmentation. 21 When used as a barrier film, the technical sensitivity is high. 22,23 The emergence of short implants provides another solution, especially in the case of insufficient vertical bone volume in the posterior teeth, but the crown-to-root ratio is imbalanced after restoration, and the long-term prognosis remains controversial.…”

“…The lack of bone wall support around the area makes it difficult to maintain the stability of blood clots and bone grafts, and it is difficult to reduce soft tissue tension in the operation area, which often leads to a series of complications, such as postoperative wound dehiscence, secondary infection, and bone graft escape.

To address the problem of insufficient bone mass in the implant area, we focused on the vertical increment of the posterior mandibular area to increase bone mass with the aid of a healing abutment. Data of patients with insufficient vertical bone height in the posterior mandibular area were collected, and vertical increment of alveolar bone operations was performed with the aid of a healing abutment. Preoperative residual alveolar bone height, immediate postoperative alveolar bone height, and 6-month postoperative alveolar bone height were recorded, with peri-implant soft tissue results 6 months after surgery using the modified plaque index and sulcus bleeding index. Twelve patients, aged 42–73 years, with an average age of 55.91 ± 11.58 years, received vertical bone augmentation in the posterior mandibular region supported by implant healing abutments. Fifteen SLA TSIII OSSTEM implants were utilized in the 12 patients; one patient failed in vertical bone augmentation at one site (H0 = 0 mm). The vertical bone augmentation effect of two patients at two sites was 0 mm < H0 < 1 mm, and the vertical bone augmentation effect of 12 sites in nine patients was H0 ≥ 1 mm. The implant success rate was 93.3%, and the mean vertical bone gain was 2.91 mm. Peri-implant soft tissue parameters are as follows: mean modified plaque index, 1.92; mean modified sulcus bleeding index, 1.21; and mean probing depth, 3.18. No clinically observable complications occurred. Bone augmentation supported by the implant healing abutment showed the characteristics of “platform transfer”, with good formation of the implant–bone interface. The bone augmentation surgery was completed at the same time as the implant placement, which reduced the pain of multiple operations and shortened waiting times. We provide a novel idea to solve the problem of insufficient vertical bone height in the posterior mandibular region.

Aim To 3‐dimensional radiographically assess the effect of titanium plate in guided bone regeneration (GBR) for the treatment of peri‐implant ridge defects in esthetic zone. Material and Methods Nineteen patients with buccal peri‐implant defects in the maxillary esthetic zone were treated with GBR using xenograft, autogenous bone, and collagen membrane. Subjects were divided into two groups: control (conventional GBR, 10 patients with 16 implants) and test (GBR with an adjunctive titanium plate; nine patients with 15 implants). Cone‐beam computed tomography (CBCT) images obtained immediately after and 5–7 months following GBR were used to assess buccal crestal bone level (BBL) and buccal bone thickness (BBT) at different implant levels. Results Thirty‐one implants in 19 patients were evaluated. Titanium plate exposure occurred in three cases (33.33%) of the test group. After 5–7 months, the mean BBL was located 1.48 ± 0.71 mm coronal to the platform in the test group and 0.90 ± 3.03 mm coronal to the platform in the control group (p = 0.03). The mean over all BBT (BBT‐M) was 4.16 ± 0.48 mm in the test group and 2.38 ± 0.97 mm in the control group (p < 0.01). More resorption occurred in the control group than in the test group regarding mean BBL (3.00 ± 3.11 mm vs. 0.78 ± 0.79 mm, respectively; p = 0.04), BBT‐M change (1.87 ± 1.59 mm vs. 0.56 ± 0.33 mm, respectively; p = 0.02), and percentage change in BBT‐M (40.69 ± 24.01% vs. 11.53 ± 5.86%, respectively; p < 0.01). Conclusion In the short‐term, titanium plate‐enhanced GBR maintained ridge dimensions better than conventional GBR did.
