In 1921, Dr. Thomas R Hinman of Atlanta, Georgia read a paper before the First district Dental Society in New York City that dealt with the management of infected teeth. Adherents of the theories of focal infection and elective localization advocated the extraction of teeth with necrotic pulps and particularly those with periapical lesions. In his presentation, Dr. Hinman overlooked the procedures of root amputation or apicoectomy (terms that were was synonymous at that time), stating that the technique had been abandoned as a failure by oral surgeons. Dr. Hinman later claimed that he had been misunderstood, and that what he really meant was that apicoectomy is only rarely successful. Out of this incident there appeared a lengthy symposium, with contributions from across the United States. While this debate ensued, the techniques of this procedure were being applied and evaluated in the European sector, with a number of treatises expounding on their versatility, acceptability, and applicability far beyond what was being addressed in the United States. This paper will focus on some of the unique historical perspectives from all parties, and clarify these perspectives relative to contemporary philosophies and rationales.

OBJECTIVE
To establish an apicoectomy guide template design and manufacturing method, based on multi-source data fusion, computer aided design (CAD) and fused deposition modeling (FDM). The feasibility of the guide template was preliminary evaluated by the in vitro model experiment.
METHODS
An extracted upper anterior tooth, after root canal treatment, was optical scanned, after which the extracted upper anterior tooth was poured in an apicoectomy plaster model. Cone-beam computed tomography (CBCT) scanning of the apicoectomy plaster model was performed, after which optical scanning of the plaster model for apical resection surgery was carried out. All of the relevant CBCT and optical scanning data of the extracted upper anterior tooth and the apicoectomy plaster model were introduced into the Geomagic Studio 2012 software. The multi-source data fusion technology was used to virtually simulate the three-dimensional positional relationship of the extracted tooth, the dentition, the alveolar bone and the gingival, based on which, the three-dimensional design of the apicoectomy guide template was completed in the Geomagic Studio 2012 software. With the technology of fused deposition modeling, the apical resection surgical guide template was three-dimensionally printed with the material of polylactic acid (PLA). Under the guidance of the surgical guide template, the root apical resection was performed on the plaster model. After the apicoectomy, the extracted upper anterior tooth was taken off from the apicoectomy plaster model and then was given the optical scanning. The apical resection length and angle were calculated by the function of distance measurement and angle measurement, and the results were compared with the preset values.
RESULTS
The length of the apical resection was 2.88 mm along the direction of the long axis of the tooth, which was 0.12 mm lower than the preset 3 mm. The included angle between the apical resection plane and the long axis of the tooth was 77.9°, 12.1° lower than the preset 90°.
CONCLUSION
This study successfully established a digital design and production method of apicoectomy guide template by combing the multi-source data fusion, CAD and FDM technology. The design route and the production method are feasible. The study will provide a technology and methodology reference for the development of domestic special software for the digital design of apicoectomy guide template.

Apicoectomies on molars are not performed frequently, although their success rate can reach that obtained by apicoectomies on front teeth and premolars. 86 patients were operated on between January 1976 and December 1980 at St. Radboud Hospital. Clinical and radiological re-examination could be carried out on 70 of them. In 73% of the cases, healing was complete, in 21% incomplete, and in 6% the teeth were extracted. Certain factors which possibly influenced healing and the methods of root filling are discussed.
