(1)	[158]	Park et al.	Digital technique for in vivo assessment of internal and marginal fit of fixed dental prostheses	Digital approaches to assess the misfit of fixed dental prostheses have been limited to in vitro evaluation. The present article describes a fully digital technique for the in vivo assessment of the fit of fixed dental prostheses by means of a chairside optical scanner and software for three-dimensional (3D) analysis. The 3D digital capture is performed in 3 steps: an extraoral scan of the restoration, an intraoral scan of the abutment tooth, and an intraoral registration scan of the restoration positioned on the abutment tooth.
(2)	[160]	Lin et al.	Examination of ceramic restorative material interfacial debonding using acoustic emission and optical coherence tomography	Sustainable cyclic load stresses in ceramic/dentin-bonded specimens were substantially lower than the measured SBS. Predicted S–N curve showed that the maximum endured load was 4.18 MPa passing 10^6 fatigue cyclic.
(3)	[161]	Lin et al.	Examination of ceramic/enamel interfacial debonding using acoustic emission and optical coherence tomography	The acoustic emission technique combined with OCT MPa images as a preclinical assessment tool to determine the integrity of cemented load bearing restored ceramic material. Sustainable cyclic load stresses in ceramic/enamel-bonded specimens were substantially lower than the measured SBS. Predicted S–N curve showed that the maximum endured load was 10.98 (about 34.48 N) passing 10^6 fatigue cyclic.
(4)	[162]	Madaras et al.	Material defects in ceramic crowns identification by optical coherence tomography and microCT	OCT technology can be considered an early diagnosis method of faults contained in the table structure of the ceramic crowns before inserting them in the oral cavity, by reducing the risks of a prosthetic treatment.
(5)	[163]	Fernandes et al.	Optical coherence tomography investigations of ceramic lumineers	The OCT is an effective and promising method to clinical evaluation of the cementing line in lumineers.
(6)	[164]	Gabor et al.	OCT evaluation of single ceramic crowns: comparison between conventional and chair-side CAD/CAM technologies	The marginal accuracy of all ceramic crowns fabricated with digital impression and the CAD/CAM technique is superior to the conventional impression technique.
(7)	[165]	Türk et al.	Comparison of the marginal adaptation of direct and indirect composite inlay restorations with optical coherence tomography	Within the limitations of this in vitro study, marginal discrepancies of inlay restorations were quantitatively and noninvasively evaluated by the OCT system. The following conclusions may be drawn: direct inlays presented smaller marginal gap values than indirect inlays. The marginal gap values were increased for all restorations after cementation.
