Severe caries, attrition, abrasion, erosions of anterior teeth lead to loss of anterior guidance. This in turn causes attrition of posterior teeth and loss of occlusal vertical dimension. To gain the space for esthetic rehabilitation in these cases is cha llenging task. The required space can be achieved by crown lengthening and increasing the occlusal vertical dimension within physiologic lim...
چکیده این تحقیق در بخشی از سامان عرفی شوراب چنار بگالی استان لرستان که بلوط ایرانی (quercus brantii lindl.) گونه غالب جنگل های آن است صورت پذیرفت. در مطالعه ی حاضر به منظور بررسی تاثیر عوامل توپوگرافی (ارتفاع از سطح دریا، شیب و جهت زمین) بر فاکتورهای تاج پوشش، مساحت تقریبی 1500 هکتار انتخاب گردید. سپس تعداد 147 قطعه نمونه مستطیلی به ابعاد 20 ×10 متر با استفاده از شبکه آماربرداری منظم - تصادفی ...
Partial edentulism has multiple implications in relation to function, esthetics and future rehabilitative treatment. This case report illustrates the management of a patient with extreme consequences of partial edentulism. The main clinical findings were unopposed remaining teeth, overeruption of the remaining teeth, loss of vertical dimension of occlusion, and significant disfigurement of the ...
A 46-year-old woman presented at the Department of Periodontology, University of Giessen, with mild chronic periodontitis and multiple gingival recessions in the upper jaw. Examination revealed poorly contoured metal ceramic restorations. Resulting soft tissue contours were also less than ideal from an aesthetic perspective. Oral hygiene instructions, scaling, and root planing were performed to...
This clinical report describes an interdisciplinary (orthodontic, periodontic, and prosthodontic) approach for the coordinated treatment of a patient diagnosed with peg-shaped maxillary lateral incisors, diastemata, short clinical crowns, excessive gingival display, and orthodontic malocclusion. The patient's specific esthetic expectations for the anterior maxilla were successfully met through ...
excessive gingival display can affect the total esthetics of a smile, becoming the focus instead of the frame of the smile. This can be the result of passive eruption of the gingival complex as the teeth erupt.1,2 the condition of delayed or altered passive eruption exists when the gingival complex remains positioned coronal to the cementoenamel junction with the attachment on the enamel instea...
