Immediate implantation in fresh extraction sockets. A controlled clinical and histological study in man.

BACKGROUND: Early implantation may preserve the alveolar anatomy, and the placement of a fixture in a fresh extraction socket helps to maintain the bony crest. Although a number of clinical studies exist, no histological reports show the outcome of implantation in fresh extraction sockets without the use of membranes in humans compared to implants placed in mature bone. METHODS: Forty-eight healthy patients, receiving at least 4 fixtures in each of 2 symmetrical quadrants, underwent placement of 1 experimental fixture placed in a fresh extraction socket (TI) and 1 contralateral fixture in mat

The Furlong hydroxyapatite-coated total hip replacement in patients under age 51. A 6-year follow-up study.

Forty-five Furlong hydroxyapatite-coated total hip replacements were reviewed at an average of 71 months (46-89) after surgery. Patient's average age at surgery was 46 years (31-50). The average Harris hip score at the time of final review was 89, and 38 hips (84%) had no pain (28) or only slight pain (10). Three hips were revised, none for aseptic loosening. Two cups were loose. The remainder of the cups and all the stems were radiographically stable with positive evidence of bone ingrowth and no signs of impending failure. One cup showed definite wear of the polyethylene liner. Focal progres

Timing of dental surgery in patients receiving bone-modifying agents: Medication related osteonecrosis of jaw (MRONJ) and implant outcomes in a cohort of 5,284 oncology patients within an integrated dental pathway.

BACKGROUND: Medication-related osteonecrosis of the jaws (MRONJ) is an important toxicity of bone-modifying agents (BMAs). Guidelines recommend dental assessment and risk reduction before high-dose antiresorptive therapy, but real-world data on outcomes by timing of dental procedures relative to BMA therapy remain limited [1-4]. This study evaluated MRONJ and implant outcomes according to the timing of dentoalveolar surgery within an integrated oncology-dental pathway.
