PURPOSE The location of the gingival zenith in a medial-lateral position relative to the vertical tooth axis of the maxillary anterior teeth remains to be clearly defined. In addition, the apex of the free gingival margin of the lateral incisor teeth relative to the gingival zeniths of the adjacent proximal teeth remains undetermined. Therefore, this investigation evaluated two clinical paramet...

Options for restoring a single tooth include fixed partial denture, resin-bonded restoration and single-tooth implant. In this paper, we discuss the advantages and disadvantages of these methods and factors that must be considered when choosing between them for the replacement of a single tooth. Although in some cases a fixed partial denture is the most appropriate choice, implants have the adv...

PURPOSE The aim of this study was to evaluate and compare tooth surface characteristics in extracted human molars after cervical enamel projections (CEPs) were removed with the use of three rotating instruments. METHODS We classified 60 extracted molars due to periodontal lesion with CEPs into grade I, II, or III, according to the Masters and Hoskins' criteria. Each group contained 20 specime...

The use of teeth as abutments for fixed and removable partial dentures can result in biologically destructive consequences. Teeth adjacent to edentulous spaces should exhibit improved prognoses if restorative trauma is to be avoided or minimized. Implants offer a method of tooth replacement without relying upon the surrounding dentition for support. This investigation evaluates implant survival...

PURPOSE The purpose of this study was to clarify the influence of changes of occlusal contacts on adjacent tooth displacement during articulation. MATERIALS AND METHODS The amount and direction of displacement of the maxillary left first molar and adjacent teeth were measured using a displacement transducer, Type M-3. Seven subjects were included in this study. On the maxillary left first mol...

background: low- level laser therapy has been used to stimulate the orthodontic tooth movements (otm) previously. furthermore, in the orthodontic treatments accompanying tooth extractions, the adjacent teeth move towards the extraction sites and close the space in some cases. then, the adjacent tooth movements must be prevented in the treatments requiring space. laser stimulates and at some dos...

Physiologic drift of teeth requires remodeling alveolar bone at the tooth socket wall. Remodeling must be regulated so that collagenous attachments are maintained as new tooth positions are established. Thus, alveolar remodeling must occur coincident to remodeling of the Sharpey’s fibers which are embedded within that bone. Studies suggest that these fibers are severed at resorptive sites on th...

Submit Manuscript | http://medcraveonline.com the posterior part of the jaws and consist of a disorganized mass with no morphologic resemblance to a tooth [1]. The lesions are invariably asymptomatic and are discovered on routine radiographic examinations; however, they may be associated with pathologic changes in adjacent teeth and structures such as-malformation, impaction, delayed eruption, ...

The ballista spring system is a simplified orthodontic system for treating impacted teeth. The impacted tooth is retracted by a spring that accumulates a continuous force from being twisted on its long axis. The necessary operation on the impacted tooth is simple and less traumatic. The force exerted on the tooth is vertical, without compressing the impacted tooth toward the adjacent roots. Thi...

Replacing a single missing anterior tooth can be a challenge. Many factors need to be considered when choosing the appropriate treatment. Several treatment options are well established. This case report is to present the use of a cast cobalt chrome partial denture with custom made porcelain tooth to improve aesthetic. The overall shade of the artificial tooth were nicely matched with the adjace...
