Surgical Management of Significant Maxillary Anterior Vertical Ridge Defects.

Severe vertical ridge deficiency in the anterior maxilla represents one of the most challenging scenarios in bone regeneration. Under ideal circumstances, guided bone regeneration in combination with soft tissue management has shown predictable esthetic and functional outcomes. Success largely relies on primary wound closure during and after the surgical procedure.

Facial gingival tissue stability following immediate placement and provisionalization of maxillary anterior single implants: a 2- to 8-year follow-up.

Purpose: This is a follow-up of an earlier 1-year prospective study on implant success rates and the peri-implant response after immediate placement and provisionalization of single implants in the esthetic zone. The effects of gingival biotype on the peri-implant tissues were also evaluated.

Materials And Methods: Thirty-five patients were evaluated clinically and radiographically at presurgical examination (T0), immediately after immediate implant placement and provisionalization (T1), 1 year after implant surgery (T2), and the latest follow-up appointment (T3).

Immediate loading of unsplinted implants in the anterior mandible for overdentures: a case series.

Purpose: This case series evaluated the implant success rate and peri-implant tissue response of immediately loaded unsplinted implants retaining a mandibular overdenture.

Materials And Methods: Eight completely edentulous patients (five men, three women) with a mean age of 69.1 years were included in the study.

Immediate loading of two freestanding implants retaining a mandibular overdenture: 1-year pilot prospective study.

Purpose: The aim of this 1-year pilot prospective study was to evaluate the implant success rate, peri-implant tissue response, and complications associated with the immediate loading of two freestanding implants retaining mandibular overdentures.

Materials And Methods: Ten adults with a mean age of 59.7 years (range, 43 to 78 years) underwent treatment that included a maxillary removable complete denture opposing a mandibular removable overdenture retained by two freestanding, threaded, titanium oxide-surface implants with a 3-mm machined collar (n = 20 implants).

Study of an experimental microthreaded scalloped implant design: proximal bone healing at different interimplant distances in a canine model.

Purpose: The aim of the present study was to evaluate the validity of a new experimental microthreaded scalloped (MTS) implant design in comparison to a conventional flat-top (FT) implant by measuring the proximal bone loss at different interimplant distances in a canine model.

Materials And Methods: MTS implants were placed in one side of the posterior mandible and conventional flat-top (FT) implants were placed in the other side of the mandible in 10 beagle dogs. In five dogs, four each of the MTS and FT implants were placed with an interimplant distance of 2 mm.
