“…In fact, starting from 1992, when the concept of guided implant insertion was introduced, the design of the surgical guides proposed by the various software manufacturers or implant companies remained substantially the same and did not evolve [6, 23]. Most of the tooth-supported surgical guides currently available still remain resin bites with extended surfaces, which rest on the adjacent teeth, completely covering the area below; the preparation of the implant site and the implant positioning are still carried out by means of a metal sleeve positioned inside the template, in which the surgeon inserts diameter reducers [2, 4, 6, 24].…”

“…The scientific literature has amply reported through systematic reviews [9, 16] that guided surgery is rather inaccurate, with deviations between the planned and the real (actual) position of the implants. The lack of stability of the template depends mainly on its design (and, obviously, the acquisition and prototyping tools used to fabricate it) [21, 24]; the material used may have a role too. In any case, the conventional templates covering the whole dentate arch do not allow the surgeon to have adequate visibility of the operative field (for example, they do not allow him to raise a flap to preserve the keratinized mucosa, which plays an important role in peri-implant health over time) [6].…”

BackgroundThis retrospective clinical study aims to present results of experience with a novel guided surgery system with a sleeveless, open-frame structure, in which the surgical handpiece (not the drills used for preparation) is guided.MethodsThis study was based on an evaluation of the records of partially edentulous patients who had been treated with a sleeveless open-frame guided surgery system (TWIN-Guide®, 2Ingis, Brussels, Belgium), between January 2015 and December 2017. Inclusion criteria were patients with good systemic/oral health and a minimum follow-up of 1 year. Exclusion criteria were patients who had been treated without a guide, or with a guide with sleeves, patients with systemic/oral diseases and who did not have a follow-up of 1 year. The main outcomes were surgical (fit and stability of the surgical guide, duration of the intervention, implant stability, and any intra-operative or immediate post-operative complication), biologic, and prosthetic.ResultsThirty-eight patients (24 males, 14 females; mean age 56.5 ± 14.0 years) were included in the study. These patients had been treated with 110 implants inserted by means of 40 sleeveless, open-frame guides. With regard to fit and stability, 34 guides were excellent, 4 acceptable, and 2 inadequate for use. The mean duration of the intervention was 23.7 (± 6.7) minutes. Immediately after placement, 2 fixtures were not stable and had to be removed. Two patients experienced pain/swelling after surgery. The 108 surviving implants were restored with 36 single crowns and 32 fixed partial prostheses (24 two-unit and 8 three-unit bridges); these restorations survived until the 1-year follow-up, with a low incidence of biologic and prosthetic complications.ConclusionsWithin the limits of this study, this novel guided surgery system with sleeveless, open frame–structure guides seems to be clinically reliable; further studies on a larger sample of patients are needed to confirm these outcomes.

“…The digital workflow presented allows the surgical position of implants to be guided by the design of the future prosthesis. Superimposition of photographs, casts, CBCT, and extraoral scanning have been determined to be reliable procedures . Meanwhile, 3D digital smile design based on the face scan helps to achieve excitement and approval from patients when proposing treatment options, but the current software with a fixed smile line cannot simulate lateral profiles after retraction or protrusion of anterior teeth.…”

Three-dimensional (3D) printing is the process of building 3D objects by additive manufacturing approach. It is being used in endodontics, periodontology, maxillofacial surgery, prosthodontics, orthodontics, and restorative dentistry, but our review article is focused on periodontal application. A detailed literature search was done on PubMed/Medline and Google Scholar using various key terms. A total of 45 articles were included in this study. Most of the studies were in vitro, preclinical, case reports, retrospective, and prospective studies. Few clinical trials have also been done. Periodontal applications included education models, scaffolds, socket preservation, and sinus and bone augmentation and guided implant placement. It showed better alveolar ridge preservation, better regenerative capabilities, greater reduction in pocket depth and bony fill, ease of implant placement in complex cases with greater precision and reduced time with improved outcome and an important tool for education and training using simulated models.
