In-Vitro Study of the Contamination Remaining on Used Healing Abutments after Cleaning and Sterilizing in Dental Practice.

Background: Reuse or "recycle" of dental implant healing abutments in clinical practice is common, primarily for economic rational.

Purpose: To determine of this practice results in reuse of components that carry with them some degree of contamination between patients, even following thorough cleaning and sterilization.

Materials And Methods: One hundred healing abutments were collected from eight clinicians following patient use.

Bone regeneration using rhBMP-2 induction in hemimandibulectomy type defects of elderly sub-human primates.

Our previous work has shown that total osseous reconstruction of large discontinuity hemimandibulectomy, critical-sized defects can be achieved easily in 8-year-old Macaca fascicularis monkeys (Boyne 1996). However the literature has indicated that animal aging decreases the BMP induction of stem cells in rats and in other rodent species. It was necessarily important that the rhBMP-2 be demonstrated in non-human primates to determine if this reduction in effectiveness also existed in the higher animals phylogenetically.

Maintaining vector control during alveolar distraction osteogenesis: a technical note.

Distraction osteogenesis is a predictable method for restoring missing tissue prior to implant placement. However, pull from the soft tissue can alter the desired direction of the distraction. This article describes and illustrates techniques that are useful for maintaining the desired vector during alveolar distraction osteogenesis.

Medial approach for tibial bone graft: anatomic study and clinical technique.

Purpose: The purpose of this study is to quantify the amount of bone graft material present in the proximal tibia via a lateral versus a medial approach, as well as describe an alternative technique for obtaining this bone graft material. A quantitative anatomic and statistical analysis and comparison are presented. The goal of this study is to demonstrate the advantages and simplicity associated with utilizing the proximal tibia as a bone graft harvest site in oral and maxillofacial surgery via a medial approach.
