A novel guided surgery system with a sleeveless open frame structure: a retrospective clinical study on 38 partially edentulous patients with 1 year of follow-up

Abstract

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 Modern and Digital Transformation of Oral Health Care: A Mini Review

“…Most implant manufacturers require a drill guide and/or a specialized guided surgical osteotomy kit. There are only a few implant manufacturers who promote surgical guides without the need to use a drill guide and the metal sleeve (R2 Navi Guide™, Megagen, Daegu, South Korea), which empirically is proven to be clinically reliable [ 46 , 47 ].…”

Artificial intelligence in fixed implant prosthodontics: a retrospective study of 106 implant-supported monolithic zirconia crowns inserted in the posterior jaws of 90 patients

“…(A) Endoral periapical radiograph taken at the beginning of the restorative process, before the first intraoral scan, with the healing abutment in position. (B) Three years later, the crown is in function and seated with high precision over the abutment, with little or no gap (surgical [8,33], prosthetic [2-5, 10, 30] and orthodontic [34]) that will then be produced physically for clinical use but also to instruct the same software so that it 'learns' certain mechanisms, and can therefore respond or act automatically, with an overall benefit for the workflow in terms of reducing processing times and costs [9]. In the field of implant prosthodontics, for example, the new digital workflows involve the use of intraoral scanners to capture the position of the implants through the scanbody, the digital version of the old implant transfer [6][7][8][9].…”

Basics of navigation implant prosthetics planning

“…Besides, surgical procedure is performed with continuous irrigation of the osteotomy site. The guide uses the pattern of the open frame, giving the clinician the guidelines for the implantation in the form of two reference cylindrical bushings places on the vestibular and oral sides of the surgical guide [23,25].…”

“…Kao glavni, navode se nedovoljna preglednost operativnog polja, nemogućnost primene hirurškog vodiča u slučaju malog interokluzalnog prostora, opasnost od oštećenja ili kontaminacije svrdla prilikom prolaska kroz cilindar vođice [23]. Da bi se nadomestili pomenuti nedostaci, danas se uveliko razvija metoda ugradnje implantata primenom otvorenog vodiča (TWIN-Guide®, 2Ingis, Brussels, Belgium) [23,25]. Otvoren dizajn kompenzuje navedene nedostatke zatvorenog sistema vodiča i kompatibilan je sa svim implantološkim sistemima.…”
