This study compared bone regeneration using occlusive or perforated membranes combined with acellular collagen sponge (ACS) and recombinant human bone morphogenetic protein-2 (rhBMP-2) in a canine mandibular model. Male Beagle dogs (n = 3) received two mandibular defects each to compare ACS/rhBMP-2 with experimental (perforated group) and control (nonperforated group) membranes (n = 3 defects/group). Tissue healing was assessed histomorphologically, histomorphometrically, and through volumetric reconstruction using microcomputed tomography. The perforated group showed increased bone formation and reduced soft tissue formation compared to the nonperforated group. For the primary outcome, histomorphometric analysis revealed significantly greater total regenerated bone in the perforated group (67.08% ± 6.86%) than the nonperforated group (25.18% ± 22.44%) (P = .036). Perforated membranes had less soft tissue infiltration (32.91% ± 6.86%) than nonperforated membranes (74.82% ± 22.44%) (P = .036). The increased permeability of membranes in the perforated group potentially enabled periosteal precursor cells to have greater access to rhBMP-2.

Despite various techniques to augment KM, challenges persist in achieving stable, keratinized, and adherent mucosa, especially in the context of significant muscle pull or compromised tissue conditions. This study introduces a novel application of titanium pins for the fixation of free gingival grafts (FGGs) and apically repositioned flaps (APFs) during vestibuloplasty, aiming to overcome important limitations associated with traditional suturing methods, shorten the treatment time, and reduce patient morbidity. Three patients with insufficient KM width presented discomfort during oral hygiene care and showed inflammation around implant restorations and natural teeth. These patients underwent soft tissue augmentation using titanium pins-traditionally used in guided bone regeneration-to stabilize the FGGs and APFs. This method ensures intimate contact between the graft and the periosteum, which facilitates proper graft perfusion and revascularization, minimizes shrinkage, and reduces the risk of graft necrosis. A postoperative follow-up revealed successful graft integration, with minimal shrinkage and increased KM width and depth. The use of titanium pins allowed for reliable fixation in challenging surgical sites where traditional suturing methods were impractical due to the presence of extensive muscle pull and an unstable recipient bed. The application of titanium pins for the fixation of FGGs and APFs during vestibuloplasty provides a promising alternative to traditional suturing techniques, particularly in complex cases where the recipient bed is suboptimal for suturing. This method simplifies and shortens the procedure, offering a predictable outcome with increased mechanical stability and minimal graft shrinkage.

Cone-beam computed tomography revealed a distolingual RE with significant bone destruction around it, indicative of a through-and-through furcation defect. A treatment approach, known as vital root resection, which combined vital pulp therapy and surgical root resection, was implemented.
