Immediate Postextraction Implant Placement in Sheep's Mandibles: A Pilot Study

Abstract

Sheep have many practical advantages compared with other animal models. However, their specific oral biomechanics inherent to their constant ruminant activity accounted for a high degree of the reported implant failures. Important adaptations to the implantation technique and postoperative management will be necessary to use sheep as an animal model for future oral implant related experiments.

Immediate Implant Placement in Infected Sites: A Case Series

“…Today, the placement of implants immediately after tooth extraction has proven to be a predictable treatment strategy with a very high success rate 3 . Vlaminck et al 4 in an animal model and Cornelini et al 5 in their clinical trial have demonstrated the successful outcome of dental implants immediately placed in fresh extraction sockets, with or without the use of membranes or regenerative procedures. Schliephake et al, 6 when comparing implants immediately placed into extraction sites with or without polylactic acid membranes, from a histologic point of view, found no difference in bone–implant contact between implant sites treated with membranes and controls.…”

Systematic review of pre‐clinical models assessing implant integration in locally compromised sites and/or systemically compromised animals

“…Four more studies reported on a sheep model [18; (Vlaminck et al. )], two monkey models with scores of 14 (Warrer et al. , Scarano et al.…”

“…Fifteen were conducted in dogs, reaching a mean score of 15.2 ± 2.8 (range [11][12][13][14][15][16][17][18][19][20]. Four more studies reported on a sheep model [18; (Vlaminck et al 2008)], two monkey models with scores of 14 (Warrer et al 1991, Scarano et al 2000) and a rat model [18; (Matin et al 2003)]. Again, information on items 9 and 11 was often not provided.…”

Evaluation of Various Positions on the Ovine Pelvis for Dental Implant Research

“…One of the most challenging problems with intraoral implant research in animals is an infection form contaminated oral cavity, which is evident in intraoral research related to pigs and dogs [8]. Intraoral dental implant studies by Vlaminck confirmed that the specific oral biomechanics inherent to a sheep's constant ruminant activity accounted for high degrees of implant failures [13,25].…”
