Vertical and horizontal ridge alterations after tooth extraction in the dog: flap vs. flapless surgery

Abstract

Evaluating ridge alterations in the vertical and horizontal dimension after 3 months of healing following tooth extraction, results for the flap and the flapless group were very similar.

Impact of immediate loading on early bone healing at two‐piece implants placed in fresh extraction sockets: an experimental study in the beagle dog

“…With respect to the impact of immediate loading on ridge alterations, our results are in agreement with those presented previously by Blanco et al. (b), where immediately loaded/immediate implants (test) were compared with unloaded non‐submerged immediate implants (control) after 3 months of healing. Results with respect to buccal bone resorption were 0.86 mm (test) and 1.3 mm (control) similarly to the M‐BC (buccal) distance of 1.17 mm (test) and 0.69 mm (control) obtained in this experiment, if we subtract the 1 mm corresponding to the prosthetic abutment.…”

“…Results from this experiment are in agreement with studies with a similar experimental design, but with one‐piece implants (Blanco et al. b, Liñares et al. ).…”

“…However, a number of experimental studies have also shown that immediate placement does not prevent bone modelling that takes place after tooth extraction (Ara ujo & Lindhe 2005, Ara ujo et al 2006a, b, Vignoletti et al 2009b, Caneva et al 2010a. This may result in a diminished dimension of the ridge (Blanco et al 2011a) and lead to unaesthetic results in certain situations (Evans & Chen 2008, Kan et al 2011. Thus, a number of techniques have been described to try to minimize bone loss after tooth extraction, but still a horizontal and vertical reduction of the ridge occurs, although only to a limited extent (Darby et al 2009).…”

“…39 Moreover, during the initial phase of regeneration, the flap elevation performed to carry out tooth extractions and implant placement impairs the vascular supply to the healing site, hampering initial wound healing and possibly exerting a long-lasting effect in a dimensional reduction of the supporting bone. 40 Despite this, it was recently observed that a flapless approach in immediate implants did not substantially contribute to preventing alveolar bone resorption 41 ; hence, this issue should be addressed in future studies.…”
