Natural Tooth Pontic Using Recent Adhesive Technologies: An Esthetic and Minimally Invasive Prosthetic Solution

Anterior provisional fixed partial dentures: A finite element analysis

PURPOSE

The aim of this study was to analyze the stress distribution of fiber-reinforced composite provisional fixed partial denture utilizing a finite element analysis model.

MATERIAL AND METHODS

Three anterior teeth were collected: upper right central, left central, and right lateral incisors. A fiber-reinforced composite strip was applied to the palatal surfaces of the teeth. Micro-computed tomographic scans were acquired of the models in order to generate three-dimensional geometrical replicas. Finite element analysis was used to assess the stress distribution of fiber-reinforced composite provisional fixed partial denture using different pontic types under static applied forces that were 100, 30, and 0 N.

RESULTS

The maximum stress values were found on the unprepared natural pontic. Stress values ranged from 92.2 to 909.8, 116.4 to 646.7, and 93.8 to 393.5 MPa for composite, naturally prepared, and natural unprepared pontic, respectively.

CONCLUSIONS

Using unprepared natural tooth pontic in anterior provisional fixed partial denture to replace missing central incisors is considered superior to other types in terms of stress distribution.

Acrylic tooth splint-An immediate provisionalisation following tooth extraction; a series of case reports

Key Clinical Message

Numerous techniques for provisionally replacing a single tooth at the aesthetic zone while planning for future dental implant placement, while soft and hard tissues heal, are critical in restorative treatment strategy. The available materials, simplicity, cost, and impact on the potential implant location should be considered when evaluating the treatment choices.

Abstract

Replacement of a single anterior tooth in the aesthetic zone while planning for future implant placement is crucial to the restorative treatment plan. Several methods exist for immediate provisionalisation of the extracted tooth while waiting for soft and hard tissue healing. Although there's a myriad of possible provisionalisation methods available, each option has its advantages and disadvantages. The treatment options should weigh various factors such as the available materials, ease of fabrication, costs, and the effect on the future implant site. This article describes three clinical cases demonstrating a simple yet cost-effective technique to temporarily replace an extracted single anterior tooth, enhancing patient satisfaction and increasing compliance before receiving the definitive implant restoration. The pro and cons for each treatment option available as opposed to the technique involved in the three cases used are also described.
