“…The former manual plate molding method, which was based on an empiric growth factor, involved several steps of plate expansions involving the use of special 3D software. Next to the manual insertion of the retention pin, this method was time-consuming with a duration of up to 1.5 hours per plate series 9 , 11 . The RapidNAM-software solution for a virtual semi-automated intraoral molding plate generation created a virtual series of plates within 10–15 minutes versus approximately one and a half hours for a virtual series of plates using the conventional and manual CAD/CAM-method.…”

“…Healthy newborns with unilateral CLP (n = 14) were included in the study. Two groups were formed: one group was treated with conventional CAD/CAM-intraoral molding plates as published previously with digitally designed intraoral molding plates serving as a reference group 9 , 17 and the other group with RapidNAM-plates. In both groups, impressions were taken from the upper jaw within the first few days of life and at the end of molding therapy when primary lip closure was performed at the age of approximately 3–4 months.…”

“…The challenge remains to create an efficient and feasible virtual workflow, since simple, low-cost, and accessible software solutions are still lacking. The means of rapid prototyping allows efficient production but only once the plate has been created digitally 9 . Despite this, rapid prototyping still seems promising with regard to efficiency giving comparable clinical results to traditional methods.…”

Computer-aided design and computer-aided manufacturing (CAD/CAM) technology has been implemented in the treatment of cleft lip and palates (CLP) by several research groups. This pilot study presents a technique that combines intraoral molding with a semi-automated plate generation and 3D-printing. The clinical results of two intraoral molding approaches are compared. This is the first clinical investigation of semi-automated intraoral molding. Our study included newborns with unilateral CLP. Plaster models were digitalized and measured by two independent observers. Two methods of CAD/CAM-assisted intraoral molding were compared: (i) stepwise manual design of molding plates (conventional CAD/CAM-intraoral molding) and (ii) a semi-automated approach with an automated detection of alveolar ridges (called RapidNAM) assisted by a graphical user interface (GUI). Both approaches significantly narrowed the clefts and resulted in a harmonic alveolar crest alignment. The GUI was easy to use and generated intraoral molding devices within minutes. The presented design solution is an efficient technical refinement with good clinical results. The semi-automated plate generation with a feasible GUI is fast but allows individual adaptations. This promising technique might facilitate and foster the more widespread use of CAD/CAM-technology in intraoral molding therapy.

“…Dealing with cost analysis, several factors must be taken into account, including direct and indirect economical costs and also biological costs, in terms of patients' suffering [50][51][52]. The cost of a medium quality IOS, ranging from 15000 to 30000 EUR, is surely not comparable with the pure cost of classical impression materials and trays used during a T&P protocol, but, considering that the use of IOS diffusion is rapidly increasing because they can be used in several fields, the cost-per-single use is gradually decreasing, in direct proportion with use.…”

Evaluation of a Digital Protocol for Pre-Surgical Orthopedic Treatment of Cleft Lip and Palate in Newborn Patients: A Pilot Study

The aim of this study was to evaluate the accuracy, invasiveness and impact on clinical results of a digital oral impression protocol in the pre-surgical orthopedic treatment (PSOT) of newborn cleft lip and palate (CLP) patients undergoing primary alveolar surgical repair. Six patients were divided, according to impression technique used, into a digital (intraoral scanner (IOS)) and a non-digital (tray and putty (T&P)) group. Parents considered IOS impressions to be less invasive, compared to T&P impressions. The clinician that took all the impressions considered the IOS to be less stressful compared to the T&P method. In two T&P patients, the impression was repeated because some important anatomical details were missing, in one case due to patient regurgitation during the first attempt. No impression was repeated, and any adverse event was reported in the IOS group. There were no significant differences between these two protocols in pre-surgical alveolar gap reduction and surgical challenge. The study results indicate that this digital protocol can accelerate the production process of the passive molding plate with an instantaneous transmission of the digital impression to the dental lab, maintaining the same accuracy level and clinical outcomes of classical techniques and reducing the invasiveness of impression taking, avoiding any risk of impression material ingestion or inhalation.
