STATEMENT OF PROBLEM: Computer-engineered complete dentures (CECDs) have significant potential as shown by recent reports of outcomes and specific applications. An understanding of complications and quality assessment factors associated with CECDs from compiled data is lacking in published reports. PURPOSE: The purpose of this systematic review was to determine the clinical complications and quality assessments related to CECDs. MATERIAL AND METHODS: Electronic searches of publications in English from January 1984 to September 2016 were performed in MEDLINE and Cochrane databases, with the results enriched by manual searches and citation mining to address 2 population intervention comparison outcome (PICO) questions: what are the clinical complications associated with CECDs, and what are the quality assessments with CECDs? RESULTS: A review of 5 selected articles (limited data) on CECDs revealed patient dissatisfaction related to overall outcome (25...

BACKGROUND AND PURPOSE: Cephalometric and arch measurements might predict the occurrence of a palatally-displaced impacted maxillary canine (PDC). Despite their clinical importance, studies in this regard are limited and controversial. METHODS: In this case-control study, 35 PDC patients and 77 controls aged over 13 years were examined. Eleven cephalometric measurements: N-S, ANS-PNS, ANS-N, S-N-ANS, facial angle (FH/NPog), SNA, SNB, Y-axis (SN/SGn), gonial angle, Go-Gn/SN, and Jarabak Index were performed...

Patients with Down syndrome can present with a variety of oral manifestations such as hypodontia, periodontal disease, premature tooth loss, reduced salivary flow, crowding of teeth in both arches, and decreased occlusal vertical dimension. The intellectual ability of people with Down syndrome varies widely. They present with a mild-to-moderate intellectual disability that restricts their ability to communicate and adjust to their environment, which can add complexity in the overall dental treatment. There is little information in the literature regarding the prosthodontic rehabilitation for patients with Down syndrome in combination with dental implant placement...

Occlusal reconstruction is a complex sequential treatment. The treatment may involve changes in occlusal vertical dimension and the full dental arch occlusal surface reconstruction. In this paper, we discussed the most concerned aspects of prosthodontists during the occlusal reconstruction sequential treatment, how to determine the suitable occlusal vertical dimension, rebuilding of occlusal plane, and consideratiom of temporomandibular joint disorders during reconstruction treatment. The prosthodontists should adopt the multidisciplinary collaboration mode of thinking in analysis, design, treatment, and restoration processes, regarding patients' individual characteristic through the occlusal reconstruction sequential treatment, and to reach healthy, functional, aesthetic outcome eventually...

BACKGROUND: Malocclusion in the vertical and sagittal planes is easy to observe whereas it is difficult to diagnose malocclusion in the transverse plane. There are yet no criteria defining a normal transverse occlusion. AIM: The aim of this study was to identify a ratio that defines a normal transverse occlusion. STUDY DESIGN: This was a retrospective study. MATERIALS AND METHODS: A total sample of 151 maxillary dental models (M = 55, F = 96) in the age range of 12-16 years were randomly selected, with 73 models in control group and 78 in the study group...

Monique Raberin
INTRODUCTION: The surgical protocols are based on arches preparation before or immediately after the surgical phase. Incisor guides normalization is achieved by incisor decompensation in three dimensions. Place and extend of surgical movements depend on the incisor position obtained at the end of orthodontic preparation. Extraction versus non extraction depends on incisor position planning. Orthognathic surgery induces muscular and temporo-mandibular joint stress which can cause temporo mandibular dysfunction (TMD)...

BACKGROUND AND OBJECTIVES: Radical excisions of the rectum often result in large perineal and intrapelvic defects. Compromised wound healing can delay adjuvant therapies and limit the patient's prognosis. With current treatment, integrity of the abdominal wall may be maintained. The defect geometry is unique and requires extensive volume for reconstruction. This study describes the surgical technique and reports clinical outcomes of fasciocutaneous posterior thigh flaps as preliminary data for this indication...

Reduced volume of the internal skeletal dimensions of the face is 1 of the main causes of obstructive sleep apnea, and attention to patients' airways is necessary when planning orthognathic treatment. This study aims to describe changes in upper airway volume following virtually planned orthognathic surgery.A retrospective pilot study was designed with 30 randomly selected patients (10 men and 20 women, aged 23.1 ± 6.8 years, molar-relations: 15 neutral, 8 distal, and 7 mesial). Cone-beam computed tomography scans were performed before surgery and 1 week following surgery...

Implant-supported fixed complete dental prostheses have been associated with a high implant success rate in long-term studies. However, they have also been associated with a high frequency of prosthetic complications. The most frequent and primary prosthetic complication has been the fracture or wear of the occlusal surface of acrylic resin teeth that are typically attached to a metal framework. The design of the framework in this clinical report involved the incorporation of metal occlusal surfaces for the posterior first molars to the framework...

Various attempts have been made to transfer the transverse hinge axis and mandibular movement pattern to the mechanical articulator and to fabricate dental prostheses with the fewest errors. However, the occlusal adjustment of a dental prosthesis is always necessary to ensure a precise intraoral fit even when the facebow transfer technique is used in the cast mounting procedure. This is because the true hinge axis is not obtained when the facebow is applied to a patient who exhibits a variable mandible movement pattern rather than a single rotational axis...

This clinical report illustrates a multidisciplinary approach for the rehabilitation of a young adult patient affected by a bilateral edentulous space and an anterior deep bite. The patient required orthodontics and surgical corticotomy and implantology (both performed with a piezo device). A multidisciplinary planning approach, including orthodontics, oral and periodontic surgery, and restorative dentistry, has an important role in the final outcome of treatment. In fact a dental class I occlusion has been established only on the right side...

PURPOSE: To hypothesize a new theory based on soft tissue reference points on lateral profile photographs (LPPs) for determining the vertical dimension of occlusion (VDO), as there is need to explore for simple strategies. MATERIALS AND METHODS: Fifty-three participants in the age range of 20-27 years who met the inclusion criteria were recruited. LPPs were taken for all participants using standard protocol and duplicate copies obtained, on which five soft tissue reference points, nasion (Stn), subnasale (Stsn), porion (Stp), gnathion (Stgn), and gonion (Stg) (Stg prenoted on the face) were marked and joined to form angles; distance between Stsn and Stgn was considered as VDO in LPP (VDO-LP)...
