Cross bite molar single

BACKGROUND: Early transition from breastfeeding and non-nutritive sucking habits may be related to occlusofacial abnormalities as environmental factors. Previous studies have not taken into account the potential for interactions between feeding practice, non-nutritive sucking habits and occlusal traits. This study assessed the effects of breast-feeding duration, bottle-feeding duration and non-nutritive sucking habits on the occlusal characteristics of primary dentition in 3-6-year-old children in Peking city...

STATEMENT OF PROBLEM: It is unknown whether dental implant systems with a platform-switched configuration have better periimplant bone stress distribution and lead to less periimplant bone level changes. PURPOSE: The purpose of this study was to quantitatively investigate interfacial stress and stress distribution in implant bone in 2 implant abutment designs (platform-switched design and conventional diameter matching) by using a nonlinear finite element analysis method...

Bite force at different levels of clenching and the corresponding electromyographic (EMG) activity in jaw-closing muscles were recorded in 16 healthy women before, during and after painful stimulation of the left masseter muscle. Experimental pain was induced by infusion of 5·8% hypertonic saline (HS), and 0·9% isotonic saline (IS) was infused as a control. EMG activity was recorded bilaterally from the masseter and temporalis muscles, and static bite force was assessed by pressure-sensitive films (Dental Pre-scale) at 5, 50 and 100% of maximal voluntary contraction (MVC) during each session...

PURPOSE: To record, determine and discuss the gender influence on the overall prevalence of occlusal characteristics of primary dentition of 4- to 6-year-old children of Bagalkot City, India. MATERIALS AND METHODS: A total of 1000 children (583 boys and 417 girls) 4 to 6 years old were evaluated clinically for primary molars, primary canines, developmental spaces, measurements of overjet and overbite, crowding, anterior or posterior cross bite, midline discrepancies, lateral profile, as well as assessment of the presence of lip incompetency...

Clinical management of non-nutritive sucking habits and the resulting dentofacial changes often require multiple appliances to correct, leading to increased treatment time and costs. The aim of this paper was to introduce a single appliance combining a Teflon roller, a slow palatal expander, and a tongue crib appliance that is designed to correct the: (1) sucking habit; (2) anterior open bite; (3) posterior crossbite; (4) tongue thrust; and (5) molar relationships without the need for multiple treatment strategies...

A case of Ekman-Westborg and Julin trait and endodontic treatment of a macrodontic lateral incisor with a necrotic pulp and periradicular pathosis presented in a 21-year-old woman. Clinical and radiological findings suggesting the Ekman-Westborg and Julin trait included multiple macrodontia, multituberculism, and single conical molar roots. Orthodontic problems such as mandibular prognatism and anterior and posterior cross-bite and other minor dental morphological changes were also found. Periradicular healing after endodontic treatment was followed by standardized periapical x-ray series, and signs of healing were observed at the 9 months postoperative control...

STATEMENT OF PROBLEM: In some patients, the pattern of missing teeth may require the use of a fixed partial denture (FPD) with an intermediate pier abutment. Information is needed regarding the biomechanical behavior and the position of a nonrigid connector for this treatment option. PURPOSE: The purpose of this study was to evaluate, by means of finite element method (FEM), the effects of rigid and nonrigid design types on stress distribution for 5-unit FPDs with pier abutments...

Talon cusp is an uncommon dental anomaly referring to an accessory cusp projecting from the cingulum area, or cemento-enamel junction of maxillary or mandibular anterior teeth, in both the primary and permanent dentition. This paper reports a rare case of talon cusp affecting the mandibular right central incisor and maxillary right lateral incisor, together with other dental abnormalities, viz. an inverted impacted migrating mandibular right second premolar; complete agenesis of the maxillary and mandibular third molars, the maxillary right second permanent molar, and the mandibular left permanent central incisor; severe crowding; deep bite; hypoplastic teeth; bilateral reverse cross-bite in the premolar region; and a retrognathic mandible...

This study considered the loading configuration of intact teeth by using finite element analyses to rationalize the clinical and biologic advantage inherent to posterior tooth shape. The biomechanical behavior of opposing molars was investigated in consideration of different loadcases simulating working, nonworking, and vertical closing micromotions starting in a position close to maximum intercuspation. The resulting stress distribution was assessed in a numerical model, reproducing 2-D buccolingual cross sections of maxillary and mandibular molars...

OBJECTIVE: This study was to investigate the effective method in the reduction of deep anterior overbite. METHODS: Twenty-nine cases of three-degree deep anterior overbite were treated by using the fixed appliances in conjunction with a small bite plate. RESULTS: It was showed that this method was significantly quicker to reduce deep overbite of anterior teeth (2.04 +/- 0.78 mm per month) and shorter to require the time of treatment (3.94 +/- 1...

The purpose of this investigation was to design and develop instrumentation to measure the anterior component of occlusal force generated by a single tooth under a known axial load. An additional objective was to quantify the distribution and dissipation of this force as it progressed anteriorly. The anterior component of the occlusal force generated by the left second molar was calculated from frictional force measurements at each contact mesial to the first molars in both dental arches. The distribution of this force and its dissipation were determined for 15 subjects...
