简要总结

Elevation of the vertical dimension of occlusion has always been a debatable issue specially using removable prosthesis. Fixed restorations have been a more predictable treatment modality in treating patients with tooth surface loss. A more conservative restoration, more retrievable, and cost effective option is proposed. Partial overlay dentures could provide a reversible and more conservative solution either by being used as a final restoration or teeth are provided with ceramic onlays instead of crowns.

详细描述

Tooth surface loss and its prevalence:

Tooth surface loss is a process that describes loss of hard tooth structure due to reasons other than caries, trauma, or developmental disorders. Lambrechts et al. in 1989 estimated that the physiological tooth surface loss per annum to be approximately between 20-38 micrometers.

More than the average amount of TSL could be described as pathological tooth surface loss. A systematic review of 186 prevalence studies reported an increase of tooth surface loss from 3% at the age of 20 to 17% at the age of 70. Another German study reported similar results.

Pathologic tooth surface loss:

Pathologic tooth surface loss can be classified into attrition, abrasion, erosion, and abfraction.

研究组 & 干预措施

partial overlay denture

Experimental

removable partial denture with a metal extension over the remaining posterior teeth raising their height to the newly proposed vertical dimension and occlusal plane

干预措施: partial overlay denture (Device)

fixed temporary crowns

Active Comparator

fixed crowns made from temporary material placed on the prepared posterior teeth to the new occlusal plane level elevating the vertical dimension to the newly proposed level

干预措施: fixed temporary crowns (Other)

结局指标

主要结局

Assesment of patient satisfaction using OHIP-14 questionnaire

时间窗: 3 months

comfort of the patient and satisfaction regarding function, speech, esthetics are assesed using OHIP-14 questionnaire, and assesment will be using a Likert scale. The Likert Scale is a 5 or 7 point scale that offers a range of answer options - from one extreme attitude to another, like "extremely likely" to "not at all likely." Typically, they include a moderate or neutral midpoint.
