Esthetic Outcomes for Immediate Implant Placement with Immediate Provisionalization in the Anterior Maxilla with Buccal Dehiscence: Results of a Comparative Pilot Study.

Purpose: The aim of this pilot exploratory cohort study was to assess the value of buccal augmentation in immediate implant placement and immediate restoration of anterior teeth in maxillae with missing buccal lamellar bone with regard to esthetic parameters, as well as soft and hard tissue level changes.

Materials And Methods: This study compared three groups of 10 patients each with immediate implant placement and immediate restoration in the anterior maxilla: (1) patients with partially to totally missing buccal bone with simultaneous augmentation with bovine collagen (test group augmented [TGA]); (2) patients with partially to totally missing buccal bone without augmentation (test group nonaugmented [TNA]); and (3) patients with intact buccal lamellar bone (control group [CG]). The pink esthetic score (PES) and the course of the peri-implant bone level after 1, 3, and 12 months were used as assessment criteria.

Accuracy of Soft Tissue Prediction of 2 Virtual Planning Systems in Patients Undergoing Intraoral Quadrangular Le Fort II Osteotomy.

Unlabelled: Virtual surgical planning (VSP) is state of the art in routine clinical work. Visualization of soft tissue changes adds important information for surgical planning. The aim of this study was to evaluate accuracy of soft tissue prediction of 2 VSP systems in patients undergoing an intraoral quadrangular Le Fort II osteotomy.

Evaluation of facial aesthetics by laypersons in patients undergoing intraoral quadrangular Le Fort II osteotomy compared with conventional Le Fort I osteotomy.

In this study we compared the aesthetic outcome of (1) Le Fort I (LFI) osteotomy and (2) intraoral quadrangular Le Fort II (IQLFII) osteotomy for surgical correction of skeletal class III dysgnathia involving midfacial deficiency. The aim was to investigate whether laypersons see differences in facial changes that occur due to variations of the osteotomy cuts. The patient collectives consisted of 23 patients in each group.

Comparison of feasibility, time consumption and costs of three virtual planning systems for surgical correction of midfacial deficiency.

Background: Today virtual surgical planning (VSP) is a standard method in maxillofacial corrective surgery and is the key to reach satisfactory esthetic outcomes. The purpose of this study was to evaluate usability of three established virtual surgical planning software applications by comparing feasibility, time consumption, and costs in a standardized workflow for a modified intraoral quadrangular Le Fort II osteotomy (IQLFIIO).

Results: A cross-sectional study was performed based on retrospective and re-planned data of patients with midfacial deficiency treated by modified IQLFIIO, using three software applications: IPS Case Designer ®, Dolphin Imaging ®, and ProPlan CMF ®.

Expression of inhibitors of apoptosis proteins in salivary gland adenoid cystic carcinoma: XIAP is an independent marker of impaired cause-specific survival.

Objectives: Inhibitors of apoptosis proteins are crucial to carcinogenesis since their expression results in evasion of apoptosis. Overexpression of inhibitors of apoptosis has repeatedly been associated with resistance to treatment and poor prognosis in various cancers. The role of inhibitors of apoptosis in adenoid cystic carcinoma of the salivary gland is still unclear.
