Purpose The rise of stereolithographic surgical guides and digital workflow, combined with a better knowledge of materials and loading principle, has enabled the placement of the temporary prosthesis at the time of implant placement. This scoping review aimed to assess the current knowledge available on stackable guides. Methods The review focused on fully edentulous or requiring total edentulism patients. The procedure studied was the use of stackable guides for edentulous patients in order to place immediate temporary prostheses. The clinical endpoint was immediate placement of the provisional prosthesis after surgery combined with a prior bone reduction using a stackable guide. Results 12 case reports or case series articles met inclusion criteria, which did not allow an analysis by a systematic review. The included studies were case reports or case series. Most of the articles showed a base stabilized by 3 or 4 bone-pins, anchored in buccal or lingual part. Regarding the accuracy of bone reduction (ranged from 0.0248 mm to 1.98 mm) and implant placement when compared to planned, only 4 articles reported quantitative data. 11 articles showed an immediate loading with the transitional prosthesis after implant placement. Conclusions There are as yet no prospective or comparative studies on the efficiency of this technique. In a reliable way, stackable guides seem to be able to guide the practitioner from the flap elevation to the placement of the temporary screw-retained implant supported prosthesis. Given the lack of studies in this specific field of guided surgery, further studies are needed to confirm the clinical relevance of this technique. Graphical Abstract

“…Of the 12 articles selected, regarding material used to manufacture surgical guides, only two articles reported metal alloy surgical guides, manufactured by selective laser melting [18,25]. In the other articles, 3D printed acrylic resin was used to manufacture all the stages of stackable guides, from basis to temporary prosthesis.…”

“…The alignment of teeth and restoration of dental health in orthodontic treatment were expected to be accompanied by the improvement of facial aesthetics [ 30 ]. Dental surgeons have been able to make virtual predictions and treatment planning with the help of 3-dimensional digital technology [ 22 , 23 , 31 , 32 ]. Studies have shown that images of different dimensions affect the aesthetic perception of smiles [ 26 – 28 ].…”

Background The aim of this study was to compare the perceptual difference of smile aesthetics between 2D photographs and 3D dentofacial images as perceived by orthodontists and graduate students. Methods Forty-eight subjects finished orthodontic treatment were recruited with 2D photographs of frontal, oblique and lateral views as well as 3D dentofacial images. Twelve senior orthodontists and 13 postgraduate students were asked to rate the 2D and 3D smile simulations based on visual analog scale (VAS) and to vote for smile features that affect the attractiveness of smile. At the end, they completed a questionnaire about their views on different smile simulations. Wilcoxon signed-rank, Bland–Altman analysis, and multiple linear regression were used to compare the ratings and votes of smile perception between raters and between records. Results Orthodontists and postgraduate students rated smile consistently with 2D photographs, while orthodontists tended to give a higher rate for unattractive smiles and a lower rate for attractive smiles with 3D dentofacial images. The 3D dentofacial images were rated significantly lower than 2D photographs and the voting of most of the smile features showed significant negative main effect on VAS scores, while the effect of demographic characteristics of raters, voting on visible width of upper dentition and buccal corridor was not significant. In addition, a significant negative main effect of commissure and facial profile was found on the rating discrepancy between 2D and 3D images. Conclusions Senior orthodontists tend to perceived 3D images more conservatively in smile evaluation. 3D dentofacial images were rated lower than 2D photographs and most of the smile features affect the aesthetic perception of smile. The perceptual difference of commissure and facial profile contributed to the lower ratings in 3D dentofacial images.

“…28 Metallic or polymeric stackable implant surgical guides have been described to translate the planned alveoloplasty before implant placement, implant positions, and tooth positions for fabricating a screw-retained interim prosthesis. [29][30][31] In these designs, stackable surgical implant guides have been retained by surface contact or with anchor pins.The present article describes the digital workflow to additively manufacture a magnetically retained and stackable implant surgical guide aimed at increasing the stability of a stackable implant surgical guide and the accuracy of implant placement. The technique is illustrated on a 52-year-old woman who was referred to restore her mandibular dentition.…”
