Ridge preservation using a composite bone graft and a bioabsorbable membrane with and without primary wound closure: a comparative clinical trial.

Background: The aim of this single-masked, randomized controlled clinical trial is to compare hard and soft tissue changes after ridge preservation performed with (control, RPc) and without (test, RPe) primary soft tissue closure in a split-mouth design.

Methods: Eleven patients completed this 6-month trial. Extraction and ridge preservation were performed using a composite bone graft of inorganic bovine-derived hydroxyapatite matrix and cell binding peptide P-15 (ABM/P-15), demineralized freeze-dried bone allograft, and a copolymer bioabsorbable membrane.

Intraosseous anchorage of dental prostheses: an early 20th century contribution.

A thorough literature review of root form implants yielded a paucity of information regarding the true pioneers of this discipline. Numerous articles have been written on the history of endosseous implants, although little information is available describing the individuals to whom we attribute the major developments in implant dentistry. This article will present information regarding significant contributors to modern-day implant dentistry.
