Anderson J, Wealleans J, Ray J. Endodontic applications of 3D printing. International Endodontic Journal.Computer-aided design (CAD) and computer-aided manufacturing (CAM) technologies can leverage cone beam computed tomography data for production of objects used in surgical and nonsurgical endodontics and in educational settings. The aim of this article was to review all current applications of 3D printing in endodontics and to speculate upon future directions for research and clinical use within the specialty. A literature search of PubMed, Ovid and Scopus was conducted using the following terms: stereolithography, 3D printing, computer aided rapid prototyping, surgical guide, guided endodontic surgery, guided endodontic access, additive manufacturing, rapid prototyping, autotransplantation rapid prototyping, CAD, CAM. Inclusion criteria were articles in the English language documenting endodontic applications of 3D printing. Fifty-one articles met inclusion criteria and were utilized. The endodontic literature on 3D printing is generally limited to case reports and pre-clinical studies. Documented solutions to endodontic challenges include: guided access with pulp canal obliteration, applications in autotransplantation, pre-surgical planning and educational modelling and accurate location of osteotomy perforation sites. Acquisition of technical expertise and equipment within endodontic practices present formidable obstacles to widespread deployment within the endodontic specialty. As knowledge advances, endodontic postgraduate programmes should consider implementing 3D printing into their curriculums. Future research directions should include clinical outcomes assessments of treatments employing 3D printed objects.

Aim To report the precision of guided access cavity preparations in relation to demographical and dental variables in 50 patients. Methodology This observational study was carried out during the period 2014–2017. The patients were consecutive referrals to a private endodontic practice. The inclusion criteria were as follows: (i) pulp space obliteration associated with signs of apical periodontitis (PAI score >3 or sensitive to percussion, (ii) teeth with pulp space obliteration in need of a post, where the referring dentist had attempted or failed to negotiate the obliterated root canal (and it was not possible to negotiate using the operating microscope within a reasonable time frame) and (iii) a surgical intervention was not justified. A published methodology for guided endodontics was used. Measures on demographical and previous dental history were analysed and related to drill path precision, being evaluated on radiographs as optimal (centre of the root canal) or acceptable (peripheral/tangential). The chi‐square test was used for analyses of correlation between predictor variables and binary logistic regression analysis using backward elimination with degree of obliteration, guided access cavity preparation depth and precision as dependent variables. Significance level was 0.05. Results Thirty‐one female (median age 65 year) and 19 males (median age 69 year) were enrolled. Overall, 88% (n = 44) of the teeth had pulp space obliteration associated with signs of apical periodontitis, whereas the remaining teeth were in need of a post. The pulp space obliterations were longer in maxillary compared with mandibular teeth (P = 0.024). The performance of the drill path in mandibular teeth versus maxillary teeth resulted in a significantly greater number of optimal precision scores (P = 0.033), and when a previous attempt at access and canal negotiation had occurred versus no attempt (P = 0.009). Even in cases with the worst outcome, the technique was still successful clinically. Conclusions The clinical implementation of guided root canal treatment in fifty serial cases of single‐rooted teeth with pulp space obliteration was associated with a precision that in all cases led to the location and negotiation of the root canal and completion of the treatment.

“…The concept of Microguided Endodontics was described by Connert et al (2018) who used this technique on mandibular central incisors. They used a small diameter bur (0.85 mm) in contrast to the bigger sizes that have been used in the past, ranging from 1 to 1.5 mm , van der Meer et al 2016, Mena-Alvarez et al 2017 hence the name 'Microguided Endodontics'. In the present case, a small diameter size bur (0.8 mm) was used because of the smaller root size of the lateral incisor, to achieve a minimally invasive treatment whilst maintaining as much of the root's rigidity as possible (Lang et al 2006).…”

Aim To describe a minimally invasive method to create a 3D‐printed guide to gain access to obliterated root canals on the basis of CBCT data. Summary A 85‐year‐old female ASA III was referred for root canal treatment of tooth 22. Clinically, there were no complaints, no percussion pain or sinus tract. Radiologically, the tooth had an obliterated canal with an apical radiolucency. The tooth was diagnosed with asymptomatic apical periodontitis. Microguided Endodontic treatment was performed with the help of a 3D‐printed guide. The root canal was localized initially with the aid of the 3D‐printed guide using a round carbide bur with a head diameter of 0.8 mm. Then, the canal was shaped and cleaned using mechanical rotary files under copious irrigation with 5% NaOCl, 17% EDTA and passive ultrasonic activation. A completely healed apical area of tooth 22 was visible after 6 months on periapical radiographs and small field of view CBCT. Key learning points Using the Microguided Endodontics concept, a minimally invasive access was achieved up to the middle of the root, in a maxillary lateral incisor with pulp canal obliteration (PCO) and apical periodontitis. This technique is a valuable tool for the negotiation of PCO, reducing chair time and risk of iatrogenic damage to the root.

Endodontic treatment of dens evaginatus by performing a splint guided access cavity

Abstract: Stereolithographed splints allow performing a guided and conservative access cavity of teeth affected by dental malformations whereas digital technology allows us to esthetically reconstruct a tooth in a single session.
