Selection of anterior teeth depends mainly on Leon William theory that hypothesizes the presence of harmony between the face and inverted central incisor forms. If this theory is approved mathematically then the central incisor form and width could be predicted and calculated with acceptable precision in clinical practice. The purpose of this study was to predict the tooth form and mesiodistal ...

OBJECTIVE The aim of this study was to clarify the morphological differences in the mandibular arches of Turkish and North American white subjects. METHODS The sample included 132 Turkish (34 Class I, 58 Class II, and 40 Class III) and 160 North American (60 Class I, 50 Class II, and 50 Class III) subjects. The most facial portion of 13 proximal contact areas was digitized from photocopied im...

STATEMENT OF PROBLEM Little information is available about the buccal gingival level of multiple implant restorations. PURPOSE This study was aimed to evaluate the relationship between width and height of buccal soft tissue around single and 2 adjacent implant restorations. MATERIAL AND METHODS Four implant restoration groups (first and second molars, single second molars, posterior single ...

Optimization of machining parameters for improving the machining efficiency is become important, when high capital cost NC machines have been employed for high precision and efficient machining. The strategy is to minimize the production time and cost by optimizing feed per tooth, speed, width of cut, depth of cut and tool diameter by satisfying all the constraints such as maximum machine power...

A ffiliation: Associate Professor, Dept. of Periodontics & Oral Implantology, Swami Devi Dyal Hospital & Dental College, Barwala, Panchkula, Haryana, India. Email: [email protected] The concept of Biologic Width has been widely described by periodontists and restorative dentists. An adequate understanding of relationship between periodontal tissues and restorative dentistry is paramount to ens...

Dental implants are becoming the treatment of choice to replace missing teeth, especially if the adjacent teeth are free of restorations. When minimal bone width is present, implant placement becomes a challenge and often resulting in recession and dehiscence around the implant that leads to subsequent gingival recession. To correct such defect, the author turned to soft tissue autografting and...

This study aimed at evaluating measurements relative to the mesiodistal crown width and enamel thickness of maxillary first bicuspids. The sample consisted of 40 extracted sound bicuspids (20 right and 20 left), selected from white patients (mean age: 23.7 +/- 4.2 years), who were treated orthodontically with tooth extraction at a private clinic in São Paulo, SP, Brazil. All teeth were embedded...

F ollowing extraction of a natal or neonatal tooth, continued growth of the dental papilla may occur and a tooth-like form may develop.'^ This report describes an atypical tooth form (probably the result of continued growth of the retained dental papilla) that abscessed and may have caused delayed eruption of the adjacent primary lateral incisor. A 13-month-old white male presented to the autho...

OBJECTIVES The aim of this study was to evaluate the influence of the crown shape on the outcomes of root coverage procedures. MATERIAL AND METHODS Eighty patients with Miller class I gingival recessions in maxillary canines or premolars were selected. The recession areas were treated using the subepithelial connective tissue grafting. The following clinical parameters were analyzed: crown le...
