Abstract
Marginal Adaptation of Composite Overlays Based on two Methods of Impressions; Conventional Technique and Digital Scanner. An in vitro Study
Highlights
Indirect composite restorations such as overlays are used to cover endodontically treated teeth and protect the teeth against fracture [1]
One group had impressions made with silicone and the restorations made by the laboratory technician; in the other group an intraoral scanner took the impressions and the restorations were made by CAD/CAM
The best results were obtained in the occlusal surface (p=0.016 scanner; p
Summary
Indirect composite restorations such as overlays are used to cover endodontically treated teeth and protect the teeth against fracture [1] They copy the occlusal anatomy and the marginal adaptation of the tooth [2], preventing the entrance of fluids and bacteria inside the restoration, reducing sensitivity, plaque accumulation [3], bacterial invasion and secondary caries [4]. Improved scanner technology over the last 20 years means that there is an alternative for taking intraoral impressions [7] Their use has resulted in an improvement in impression taking, providing a better marginal adaptation compared to the conventional technique and leading to an improvement in patient satisfaction [7,8,9]
