Subcrestal placement of dental implants with an internal conical connection of 0.5 mm versus 1.5 mm: Three-year after loading results of a multicentre within-person randomised controlled trial.

Purpose: To evaluate whether there are some clinical benefits by placing single dental implants either 0.5 mm or 1.5 mm subcrestally in healed bone crests.

Subcrestal placement of dental implants with an internal conical connection of 0.5 mm versus 1.5 mm: Outcome of a multicentre randomised controlled trial 1 year after loading.

Purpose: To evaluate whether there are some clinical benefits by placing single dental implants either 0.5 or 1.5 mm subcrestally in healed bone crests.

Histological evaluation, in rabbit tibiae, of osseointegration of mini-implants in sites prepared with Er:YAG laser versus sites prepared with traditional burs.

Objective: The aim of this study was to evaluate the different bone reactions in rabbit tibiae after the insertion of mini-implants by using two different techniques of site preparation: the superpulsed Er:YAG laser (VPS system) versus the traditional technique with burs.

Methods: One mm wide and 2 mm long implant sites were made in the tibiae of 12 rabbits (8 for each tibia): the authors used an Er:YAG laser with a sapphire tip on a contra-angle hand piece with a 1.0 mm diameter in a VPS mode (with 200 mJ and 30 Hz) to make 4 bone sites and a calibrated traditional bur to drill the other 4 sites in each tibia.

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.

Reduction of autogenous bone graft resorption by means of bio-oss coverage: a prospective study.

Bone grafting may be required prior to implant placement, at the time of implant placement, or subsequent to it. The aim of this study was to compare the healing of onlay block grafts when deproteinized bovine bone coverage was used with the healing of the grafts without such coverage. The purpose was a clinical evaluation of deproteinized bovine bone's ability to reduce grafted bone resorption.

Individual skeletal models and preoperative simulation in advanced osseointegration: a case report.

This article presents a new diagnostic and simulative method, PSM LAB-MACHINE, with the aim of the anatomic reproduction of skeletal components of the facial skeleton. The importance of surgical predetermination with the possibility of simulating the planned surgical strategies is here evaluated. The described clinical case demonstrates the importance of planning in the reconstructive surgery of the maxillofacial district, using solid structures as individual skeletal models.
