PURPOSE: Preoperative planning of the implant position as part of a coordinated prosthetic and surgical concept is becoming increasingly important regarding function and esthetics. The aim of this study was to investigate the transmission accuracy of template fixation during surgery in edentulous arches with hand fixation in comparison to intermediary screw fixation. MATERIALS AND METHODS: Preoperatively, 10 implant positions were planned using computed tomography (CT) with the system med3D for implant placement in four mandible models of the Goettingen study model, using a prosthetic diagnostic template...

The purpose of this paper is to present and discuss a simple and low-cost clinical approach to correct an asymmetric skeletal Class III combined to an extensive dental open bite that significantly compromised the occlusal function and smile aesthetics of an adult male patient. The patient did not accept the idealistic surgical-orthodontic treatment option, neither the use of temporary anchorage devices to facilitate the camouflage of the asymmetrical skeletal Class III/open bite. Therefore, a very simple and inexpensive biomechanical approach using sliding jigs in the mandibular arch was implemented as the compensatory treatment of the malocclusion...

Mandibulo-maxillary fixation (MMF) is indispensable for mandibular fracture treatment. Various means for MMF have been proposed, of which arch bars are widely considered to be the mainstay. However, disadvantages to this method have initiated a quest for an alternative, leading to the introduction of MMF screws. MMF screws have frequently been criticized for poor stability of fracture sites, root damage, hardware failure, and nerve damage. We retrospectively evaluate the FAMI (Fixation and Adaptation in Mandibular Injuries) screw in mandibular fracture treatment by scanning for clinically and radiologically visible complications...

Occlusal and esthetic rehabilitation of jaw deformities in patients with partially edentulous maxilla are challenging procedures. This article describes a patient involving a skeletal Class III, 36-year-old male patient with a single bilateral anterior partially edentulous maxilla resulting from injuries sustained in a motor vehicle accident; his anterior teeth had been lost for more than 10 years. His lip protruded from the lateral view due to the proclined upper incisors and mandibular protrusion.Because of the facial deformity and inadequate prosthesis of the maxilla, the prosthesis had dropped out repeatedly...

BACKGROUND: A Class II division 2 malocclusion is characterised by upper front teeth that are retroclined (tilted toward the roof of the mouth) and an increased overbite (deep overbite), which can cause oral problems and may affect appearance.This problem can be corrected by the use of special dental braces (functional appliances) that move the upper front teeth forward and change the growth of the upper or lower jaws, or both. Most types of functional appliances are removable and this treatment approach does not usually require extraction of any permanent teeth...

Orofacial dysfunction and parafunctions are responsible for many orthodontic abnormalities right from the stage of deciduous teeth.Incisor malocclusion, dental malposition and alveolar arch malformations are the most common abnormalities.Functional rehabilitation for prevention or as part of interceptive orthodontics significantly reduces the risk of appearance or progression of these abnormalities to more extensive malocclusions that are more difficult to manage.Functional rehabilitation consists of re-educating and restoring physiological orofacial functions, such as speech and swallowing, breathing and/or chewing disorders...

Objective of the study was to evaluate the clinical status of the masticatory system in young adults with full permanent dentition and no stomatognathic system complaints. The study involved 186 randomly selected people with full dental arches with normal occlusal conditions corresponding to Angle's Class I aged 18 - 21 years with an average age of 19 years. Subjects were clinically examined and temporomandibular joint (TMJ) vibrations were recorded during open-wide and close movements using BioJVA. Then, patients were categorized into groups according to Piper's classification system...

Skeletal and dental discrepancies cause asymmetric malocclusions in orthodontic patients. It is difficult to achieve adequate functional occlusion and guidance in patients with congenital absence of a mandibular incisor due to the tooth-size discrepancy. Here, we describe the orthodontic treatment of a 22-year-old woman with an asymmetric Angle Class II malocclusion, mandibular deviation to the left, and 3 mandibular incisors. The anterior teeth and maxillary canines were crowded. We used an improved superelastic nickel-titanium alloy wire (Tomy International, Tokyo, Japan) to compensate for the asymmetric mandibular arch and an asymmetrically bent archwire to move the maxillary molars distally...

The implant-prosthetic rehabilitation of edentulous upper jaws has always been complex for surgeons and dentists. The lack of bone in both vertical and horizontal dimension does not allow the correct insertion of dental implants. In addition, patients with edentulous upper and lower arch have a loss of vertical dimension of the face and an aged expression. Many surgical techniques have been proposed to increase the bone volume, height and thickness, such as the Le Fort I osteotomy, the bone grafts and the placement of dental implants...

BACKGROUND: Alveolar cleft repair is performed via bone grafting procedure to restore the dental arch continuity. A suitable bone substitute materials should possess osteoinductive and osteoconductive properties, to promote new bone formation, along with a slowly resorbable scaffold that is subsequently replaced with functionally viable bone. Calcium phosphate biomaterials have long proved their efficacy as bone replacement materials. Dentin in several forms has also demonstrated its possibility to be used as bone graft replacement material in several studies...

AIM: This case report aimed to present an orthodontic mechanic alternative for space opening in a patient missing maxillary lateral incisors, using miniplates as anchorage, associated with self-ligating brackets. BACKGROUND: Dental agenesis affects the population causing esthetic and functional damages. The prevalence of missing maxillary lateral incisors should be considered for its significant rate and negative impact on smile esthetics. CASE REPORT: This treatment was chosen based on the presence of balanced facial pattern, large canine anatomy, the need to improve dental occlusion to prevent further wear, and patient's esthetic complaint...

The endodontic treatment of maxillary third molar often poses a challenge even to an experienced endodontist because of their most posterior location in the dental arch, aberrant occlusal anatomy, abnormal root canal configuration and eruption patterns. Owing to these anatomical limitations, their extraction remains the treatment of choice for many clinicians. As we know, retaining every functional component of the dental arch is of prime importance in contemporary dental practice. This clinical case report aims to discuss the endodontic treatment of maxillary third molar with MB2 root canal separated throughout the length and exit at two separate apical foramina (Vertucci type IV) diagnosed with Cone Beam Computed Tomography (CBCT)...

The objective of this work is to describe a segmental maxillary distraction osteogenesis (SDO) with segmental Lefort I with an inexpensive device.Four patients who presented severe class III and maxillary hypoplasia due to cleft lip and palate sequel were treated. A SDO was performed using a dental-anchored Hyrax device, achieving enlargement of the upper jaw without altering speech, with adequate and stable occlusion. Dental implants in a new formed bone were installed.The authors can conclude that SDO is a good treatment alternative for patients with maxillary hypoplasia...

OBJECTIVES: With a decreased number of teeth, a reduction in chewing function can contribute to changes in food choices and ultimately impact on overall nutritional status. This study compared the impact of two tooth replacement strategies for partially dentate older patients on masticatory performance and nutritional status. METHODS: Patients aged 65 years and older were randomly allocated to two different treatment groups. For the RPDP-group (removable partial dental prostheses) each participant was restored to complete dental arches with cobalt-chromium removable prostheses...
