Guided Apicoectomy using a CAD/CAM drilling template.
International journal of computerized dentistry, 2020Co-Authors: Eveline Sutter, Martin Lotz, Dankrister Rechenberg, Bernd Stadlinger, Martin Rucker, Silvio ValdecAbstract:AIM Modern microsurgical techniques have increased the success rate of Apicoectomy relative to that of traditional approaches. This case report introduces a novel workaround for guided Apicoectomy using a patient-specific computer-aided design/computer-aided manufacturing (CAD/CAM) three-dimensional (3D)-printed template. MATERIALS AND METHODS Apicoectomy was performed on the mesial root of tooth 36 using template-guided trephine drilling, followed by retrograde filling with mineral trioxide aggregate (MTA). Initially, a cone beam computed tomography (CBCT) scan and an intraoral surface scan were imported into the planning software. After superimposition, virtual planning was performed to determine the exact localization for root resection. Subsequently, a tooth-supported drilling template was designed and 3D printed. Endodontic microsurgical approaches, including root-end cavity preparation and root-end filling, completed the surgical treatment. RESULT The apical resection was easily feasible. There were no postoperative complications. Radiological assessment after a 6-month period showed signs of reossification. CONCLUSION Guided Apicoectomy allowed precise root resection, suggesting that this technique may be advantageous in complex anatomical situations.

The use of the erbium yttrium aluminium garnet (2,940 nm) in a laser-assisted apicectomy procedure
British Dental Journal, 2008Co-Authors: A. Reyhanian, S. Parker, Joshua MoshonovAbstract:If conventional endodontic treatment is not possible or not successful, apical endodontic surgery may be indicated. New techniques, materials and technologies have been used to increase the already high success rate of root canal treatment. The purpose of this article is to describe the use of the Erbium:YAG (2,940 nm) laser in treatment of apicectomy as a central tool, with the advantages of enhanced patient comfort, better bactericidal and decontamination effects. The apicectomy and retrograde root filling procedure must be assessed as a preferred option for treatment. Successful surgical outcome will be enhanced through appropriate understanding of causative factors and surgical skill. The use of the Erbium:YAG laser in the apicectomy procedure can achieve significant pathogen reduction within the surgical site.

outcome of orthograde retreatment after failed Apicoectomy use of a mineral trioxide aggregate apical plug
Journal of Endodontics, 2015Co-Authors: Johannes Mente, Annemarie Michel, Holger Gehrig, Daniel Saure, Thorsten PfefferleAbstract:Abstract Introduction This controlled, single-center historic cohort study project evaluates treatment outcomes of a nonsurgical treatment approach after failed Apicoectomy. Methods The treatment outcomes of nonsurgical retreatment after a failed Apicoectomy were evaluated clinically and radiographically. The study cohort consisted of teeth that had received primary root canal treatment and subsequent Apicoectomy elsewhere before the patients presented with post-treatment disease. Orthograde retreatment and obturation using an apical mineral trioxide aggregate plug was performed by postgraduate students and endodontic specialists in 25 cases between 2004 and 2012. Pre-, intra-, and postoperative information and the potential effect on the retreatment outcome were evaluated and statistically analyzed using the chi-square test. Results Twenty-two patients with 23 teeth attended the follow-up examinations (recall rate = 92%). The follow-up periods ranged from 12 to 102 months (median = 35 months). Twenty teeth (87%) were classified as “success,” and 3 teeth were considered (17%) “failure.” The chi-square test confirmed that the preoperative factor “number of roots” had a statistically significant effect on treatment outcome (odds ratio = 0.08; 95% confidence interval, 0–1.76; P = .03). The factor “tooth location” was of borderline significance (odds ratio = 0.1; 95% confidence interval, 0–2.14; P = .05). Conclusions The results of the present study suggest that orthograde retreatment combined with orthograde placement of an apical mineral trioxide aggregate plug is a promising long-term treatment option for teeth with postsurgical pathosis. The success rates were higher for single-rooted teeth. The use of cone-beam computed tomographic imaging in cases of inconclusive periapical radiographs is recommended to minimize the risk of misinterpretation when assessing treatment outcome.

Apicoectomy using er yag laser a clinical study
International Congress Series, 2003Co-Authors: Atsushi Takeda, Tomoo Anjo, Masaaki Takashina, Arata Ebihara, Hideaki SudaAbstract:Surgical endodontics was performed using an Er:YAG laser on 23 patients (4 males, 19 females) exhibiting periapical pathosis. After mucoperiosteal flap reflection, osteotomy was performed over the lesion using a low-speed dental engine with a round bur (#6–8). Root-end resection was then performed using an Er:YAG laser (100 mJ, 10 pps) with copious saline coolant. The root apex cavity for the retrograde root canal filling was prepared using either an ultrasonic device or Er:YAG laser. The clinical condition of the patients was evaluated at 1 week, 1 month, and 3 months after surgery. The mean irradiation time (FS.D.) for Apicoectomy using the Er:YAG laser was 123.9F113.2 s. No adverse reactions were seen during the laser irradiation procedure, and no harmful sequelae were observed during the follow-up periods. It is concluded that Apicoectomy using the Er:YAG laser would be both safe and practical. However, improvement of the laser device to limit the operation time would offer considerable advantages.

application of er yag laser to Apicoectomy
Journal of Japanese Society for Laser Dentistry, 1997Co-Authors: Arata Ebihara, Atsushi Takeda, Yoshiaki Sekine, Hideaki SudaAbstract:ently, many studies on the application of Er: YAG laser in the dental field have been reported. Er: YAG laser can ablate dental hard tissues with small thermal damages, and is clinically applied for removal of dental caries. However, there are few studies on Apicoectomy using Er: YAG laser. The purpose of this study was to compare Apicoectomy using Er: YAG laser and the conventional cutting method in vitro.Extracted single-rooted human teeth were used in this experiment. Root resection was performed with Er: YAG laser (output energy: 70mJ10pps) or a fissure bur mounted to a micro-motor. Resected root surfaces were evaluated with scanning electron microscopy.In addition, cutting efficiency of both methods and dye penetration of the cut surface were compared. After removing the tooth crown of 10 extracted single-rooted human teeth, root canals were cleaned, shaped and obturated. Then, the samples were randomly divided into two groups. Root resection by Er: YAG laser or micro-motor was perfOrtned, and working time was counted and the cut surface area measured. Then, all the root surfaces were sealed with nail polish except the resected surface. All roots were placed into 0.1% methylene blue dye for 7 days, rinsed and air-dried. Finally, they were split and the dye penetration from the resected surface was measured and statistically analyzed.The results were as follows:1. There were no smear layer or debris left on the resected surface cut by Er: YAG laser, and the shape of the cut surface was irregular. On the other hand, both smear layer and debris were observed on the surface cut by the conventional method, and the cut surface was smooth.2. The cutting efficiency of Er: YAG laser and micro-motor was 14.8 (±7.3) sec./mm2 and 4.4 (±1.7) sec./ram2, respectively. Cutting by Er: YAG laser significantly needed more time than that by micro-motor (t-test, P<0.05).3. Dye penetration length in the Er: YAG laser group and micro-motor group from the resected surface was 0.95 (±0.37) mm and 1.07 (±0.70) mm, respectively. There was no significant difference between the two groups.(J. Jpn. Soc. Laser Dent. 8: 23-30, 1997 Reprint requests to Dr. EBIHARA)
