Novel 3D polycaprolactone scaffold for ridge preservation--a pilot randomised controlled clinical trial.

Objectives: This pilot randomised controlled clinical trial aimed to evaluate the feasibility and effectiveness of using a polycaprolactone (PCL) scaffold in fresh extraction sockets for ridge preservation. The hypothesis was that the insertion of a 3D bioresorbable PCL scaffold in fresh extraction sockets allowed for normal bone healing and better maintenance of ridge dimensions after 6 months as compared to extraction sockets without the scaffold.

Material And Methods: Thirteen patients were randomised to either the test group (N = 6) where a PCL scaffold was inserted in the tooth socket after extraction or the control group (N = 7) where no space filler was used.

Immediate repair of transected inferior alveolar nerves in sagittal split osteotomies.

Background: Injury to the inferior alveolar nerve (IAN) in orthognathic surgery is a well-documented complication with the incidence of IAN transection in sagittal split osteotomies (SSOs) ranging from 1.3% to 7.0%.
