OBJECTIVE: This paper describes changes in the characteristics of patients seeking orthodontic treatment over the past decade and the treatment they received, to identify any seasonal variations or trends. METHODS: This single-center retrospective cohort study included all patients who presented to Seoul National University Dental Hospital for orthodontic diagnosis and treatment between January 1, 2005 and December 31, 2015. The study analyzed a set of heterogeneous variables grouped into the following categories: demographic (age, gender, and address), clinical (Angle Classification, anomaly, mode of orthodontic treatment, removable appliances for Phase 1 treatment, fixed appliances for Phase 2 treatment, orthognathic surgery, extraction, mini-plate, mini-implant, and patient transfer) and time-related variables (date of first visit and orthodontic treatment time)...

BACKGROUND: There were many articles about double-barreled fibular flap for mandibular reconstruction. The upper layer bone was suit for implant placement as a new alveolar. The lower layer was necessary for contour. But the accurate relationship between the 2 layers bone was rarely reported. OBJECTIVES: The purpose of this study was twofold: to evaluate the feasibility of the novel design of the double-barreled fibular flap from virtual surgery to actual result; to evaluate the accuracy and results of occlusion-guided double-barreled fibular free flap in mandible reconstruction...

BACKGROUND: Present clinical practice broadly relies on off-the-shelf allogeneic, xenogeneic or synthetic bone biomaterials in support of sinus augmentation. Also, recombinant human bone morphogenetic protein-2 in an absorbable collagen sponge carrier (rhBMP-2/ACS) has been shown to support clinically relevant bone formation when used to augment the maxillary sinus. OBJECTIVES: To evaluate local bone formation/dental implant osseointegration following implantation of two particulate bone biomaterials using the mini-pig sinus augmentation model...

PURPOSE: To investigate the strains around mini-dental implants (MDIs) and retromolar edentulous areas when using different numbers of MDIs in order to retain mandibular overdentures. MATERIALS AND METHODS: Four different prosthetic situations were fabricated on an edentulous mandibular model including a complete denture (CD), and three overdentures, retained by four, three or two MDIs in the interforaminal region with retentive attachments. A static load of 200N was applied on the posterior teeth of the dentures under bilateral or unilateral loading conditions...

BACKGROUND: Sufficient vertical and lateral bone supply and a competent osteogenic healing process are prerequisities for the successful osseointegration of dental implants in the alveolar bone. Several techniques including autologous bone grafts and guided bone regeneration are applied to improve quality and quantity of bone at the implantation site. Depending on the amount of lacking bone one- or two-stage procedures are required. Vertical bone augmentation has proven to be a challenge particularly in terms of bone volume stability...

Overdenture as a treatment modality for both partially and fully edentulous patients is costeffective and less expensive. The purpose of the present study was to examine the newly fabricated attachments by comparing them with conventional O-ring attachment in vitro in terms of retention force and cyclic aging resistance. A total of 150 samples were prepared and divided into five groups according to the materials used (O-ring attachment, Deflex M10 XR, Deflex Classic SR, Deflex Acrilato FD, and flexible acrylic resin)...

STATEMENT OF PROBLEM: Implant-supported overdentures (ISOs) are considered a good alternative to conventional removable dentures. However, varying rates of failure have been reported in some clinical studies. Excessive stress on surrounding tissues is one of the possible causes of implant failure. As stress is transmitted to the bone through the implant, careful planning, correct number of implants, and implant positioning are keys to ensuring appropriate stress distribution. However, research of the optimal number of implants necessary to support a maxillary ISO is insufficient...

BACKGROUND: Mini dental implants (MDIs) are becoming increasingly popular for rehabilitation of edentulous patients because of their several advantages. However, there is a lack of evidence on the osseointegration potential of the MDIs. The objective of the study was to histomorphometrically evaluate and compare bone apposition on the surface of MDIs and standard implants in a rabbit model. METHODS: Nine New Zealand white rabbits were used for the study to meet statistical criteria for adequate power...

Agenesis of maxillary lateral incisors can be treated either by closing the space and substituting the canines for the missing lateral incisors or, in adults, by replacing the missing teeth with fixed prosthetics or implants. This article illustrates a method that can be used for a semipermanent implant replacement of the missing incisors in adult patients. An Aarhus mini-implant was inserted perpendicular to the palatal mucosa of the alveolar process of the edentulous area. A pontic was made at chair side of composite material around a stainless steel wire extending from the mini-implant...

This clinical case report presents the nonsurgical orthodontic treatment of a patient with skeletal Class II malocclusion, posterior crossbite, anterior open bite, accentuated dental discrepancies in both arches, and an odontoma. The proposed treatment involved maxillary expansion, extraction of atypical maxillary lateral incisors and mandibular first molars, and intrusion of maxillary teeth with the aid of mini-implants. The results obtained with these procedures included good tooth alignment, normal overbite and overjet, removal of the odontoma, and a harmonious smile...

Mini dental implants (MDI) were once thought of as transitional implants for treatment in selected clinical situations. Their reduced diameter makes them a very attractive option for patients with poor tolerance to maxillary and mandibular prostheses. Using the method of finite element analysis, a series of different designed MDI prototypes have been investigated. The prototypes differed in the geometry of implant body and/or design of implant head. The load transfer of the implant prototypes to the idealised alveolar bone has been regarded and the prototypes have been compared to each other and to a number of standard commercial implants...

Introduction: Orthodontic miniscrews are an increasingly popular choice to achieve absolute anchorage. The temporary use of miniscrews and their recent introduction have limited the debate over the biological aspect of the materials to that of the surface that permeates the field of dental implants. The aim of the present study was to investigate the integration of grade 5 titanium mini-implants with machined or sand blasted acid etched surface (SAE) under mechanical load in a rabbit tibia model of implant integration...

Diabetes mellitus (DM) has a detrimental effect on osseointegration, stability and longevity of implants due to osteoporosis. In this study, PPARγ-loaded dental implants were investigated for the improvement of osseointegration and peri-implantitis. Chitosan gold nanoparticles conjugated with PPARγ cDNA were introduced on titanium mini-implant surfaces for PPARγ release to rat mandibular. DM-induced rat mandible showed structural changes such as decreased bone mass and increased inflammatory molecules, and diminution of PPARγ expression and bone formation molecules compared to normal rats...

BACKGROUND/PURPOSE: Sufficient bony support is essential to ensure the success of dental implant osseointegration. However, the reconstruction of vertical ridge deficiencies is still a major challenge for dental implants. This study introduced a novel treatment strategy by infusing poly(D,L-lactide-co-glycolide) (PLGA) microspheres encapsulating bone morphogenetic protein-2 (BMP-2) within a gelatin/hydroxyapatite/β-tricalcium phosphate (gelatin/HA/β-TCP) cryogel composite to facilitate supra-alveolar ridge augmentation...

BACKGROUND: Total tooth loss (edentulism) can be a debilitating condition, impacting on ability to chew, speak and interact with others. The most common treatment is with complete removable dentures, which may be successful, but in the lower jaw, bone resorption that worsens over time makes denture-wearing difficult. Two dental implants in the mandible to retain the lower denture has been advocated as the gold standard of treatment, but has not been universally provided due largely to financial constraints and also patient fear...
