Histologic analysis of resorbable blasting media surface implants retrieved from humans: a report of two cases.

The purpose of this study is to evaluate the degree of osseointegration of resorbable blasting media (RBM) surface implants retrieved from humans. Three implants in the mandibular molar region that were surface-treated with RBM were retrieved from two patients. The implants were used to manufacture specimens in order to measure the bone-implant contact (BIC) ratio.

Evaluation of Soft Tissue Changes Around the Lips After Mandibular Setback Surgery With Minimal Orthodontics Using Three-Dimensional Stereophotogrammetry.

Purpose: Most reports on the surgery-first approach in skeletal Class III malocclusion have focused on the skeletal changes. The present study evaluated the soft tissue changes around the lips over time after mandibular setback surgery (MS) with minimal orthodontics (MO) using 3-dimensional (3D) stereophotogrammetry.

Materials And Methods: We performed a retrospective study of patients with mandibular prognathism who had undergone MS-MO.

Evaluation of soft tissue changes around the lips after bracket debonding using three-dimensional stereophotogrammetry.

Objective: To evaluate the changes in soft tissue around the lips after orthodontic bracket debonding using three-dimensional (3-D) stereophotogrammetry.

Materials And Methods: 3-D facial images of 20 subjects (10 men and 10 women; mean age, 26.81 ± 7.

Influence of the changes in arch width on postsurgical relapse after mandibular setback surgery with minimal orthodontics.

Purpose: Most reports on the surgery-first approach in patients with skeletal Class III malocclusion have focused on skeletal changes and treatment efficacy. This study sought to evaluate the association between the transverse changes of arch dimension and postsurgical relapse of the mandible after mandibular setback surgery (MS) with minimal orthodontic preparation (MO) without extractions (N).

Materials And Methods: This was a retrospective cohort study.

Postsurgical stability after mandibular setback surgery with minimal orthodontic preparation following upper premolar extraction.

Purpose: To compare patterns of surgical change and postsurgical relapse between patients with mandibular setback surgery with minimal orthodontic preparation (MS-MO) and those with sufficient orthodontic preparation (MS-SO) after upper premolar extraction (UPE).

Materials And Methods: Twenty-six patients were allocated to 2 groups based on the duration of presurgical orthodontic preparation: MS-MO/UPE (n = 15; 5.53 ± 3.
