The aim of this case-control study was to evaluate the influence of soft tissue thickness at implant placement (thin [< 3 mm] vs thick [≥ 3 mm]) and bone volume (abundant vs limited) on initial crestal bone remodeling of immediate postextraction and delayed (healed site) implants in immediate loading situations. A total of 67 patients with 133 implants could be evaluated, of which 77 were placed immediately after extraction and 56 in healed ridges. If sufficient bone volume is present and primary stability is achieved, immediate loading of the implant yields good clinical and radiographic outcomes, yet implants placed in healed ridges with thin soft tissues are more prone to initial crestal bone loss...

Damien Feuillet, Jean-François Keller, Kevimy Agossa
Interdental papilla reconstruction is one of the most challenging clinical procedures in periodontal plastic surgery. Several surgical approaches have been proposed but have varying degrees of success. It has long been acknowledged that the narrowness of the interdental papilla and the limited blood supply are major impediments to achieving predictable outcomes. Advances in microsurgery could offer an opportunity to overcome these anatomic and biologic barriers. The authors propose an original microsurgical technique based on interproximal tunneling combined with utilization of a customized tissue graft for interdental papilla reconstruction...

Osseointegrated dental implants have become an integral factor in the replacement of missing teeth. These implants have demonstrated long-term success for periodontally compromised patients, who require a high level of success to maintain a sense of optimism. This case report offers 32-year results of implant treatment in the maxilla and 25-year results in the mandible. Some maxillary implants suffered a few threads of bone loss, but all seven mandibular implants met Albrektsson's definition of success after 25 years...

Porous tantalum trabecular-structured metal (PTTM) has been applied to titanium orthopedic and dental implants. This study evaluated the healing pattern of bone growth into experimental PTTM cylinders (N = 24; 3.0 × 5.0 mm) implanted in the partially edentulous jaws of 23 healthy volunteers divided into four groups. Six PTTM cylinders per group were explanted, prepared, and analyzed histologically/metrically after 2, 3, 6, and 12 weeks of submerged healing. PTTM implant osseoincorporation resulted from the formation of an osteogenic tissue network that over the course of 12 weeks resulted in vascular bone volume levels in PTTM that are comparable to clinically observed mean trabecular volumes in edentulous posterior jaws...

Gingival recession can cause an esthetic impairment or dentin hypersensitivity due to root surface exposure to the oral cavity. These conditions may require specific surgical interventions to achieve root coverage. This controlled clinical trial on 20 subjects compared coronally advanced flap (CAF) technique and CAF plus subepithelial connective tissue graft (CTG) for the treatment of single maxillary gingival recession. Recession height (REC) and complete root coverage (CRC) were considered as primary outcomes...
