Abstract

Purpose: A jumping gap (JG) refers to the implant's future buccal wall; this study aims to estimate the jumping gap dimension in relation to virtual implant placement and subsequently link the implant diameter and implant position with the anatomical site.

Methods: This observational study was conducted to analyze the maxillary teeth in the esthetic zone from cone-beam computed tomography (CBCT) scans using OnDemand software. The horizontal jumping gap dimension of each tooth was assessed by subtracting the calculated virtual implant diameter from the socket dimensions.

Results: A total of 253 anterior and premolar maxillary teeth were analyzed from 52 CBCT scans. The estimated JG dimensions were 1.23 ± 0.59 mm, 1.80 ± 0.64 mm, 3.02 ± 0.69 mm, for central incisors, lateral incisors and canines respectively, 3.70 ± 0.68 mm for the first premolars showing the highest horizontal gap and 3.19 ± 0.88 mm for second premolars. The incisors showed the smallest horizontal gap compared to the canines and premolars.

Conclusions: In terms of JG, immediate implant placement is more favorable at the canine and premolar sites. By contrast, the incisors sites should be handled with extreme caution, where the use of narrower implants is advisable when necessary.

美学区即刻种植体植入的跳跃间隙：使用锥束计算机断层扫描进行虚拟种植规划。

目的：跳跃间隙（JG）是指种植体未来的颊侧壁；本研究旨在估算与虚拟种植体植入相关的跳跃间隙尺寸，然后将种植体直径和种植体位置与解剖部位联系起来：这项观察性研究使用 OnDemand 软件，通过锥束计算机断层扫描 (CBCT) 扫描分析了美容区的上颌牙齿。通过从牙槽窝尺寸中减去计算出的虚拟种植体直径，评估每颗牙齿的水平跳跃间隙尺寸：通过 52 次 CBCT 扫描，共分析了 253 颗上颌前磨牙和前臼齿。中切牙、侧切牙和犬齿的 JG 估计尺寸分别为 1.23 ± 0.59 mm、1.80 ± 0.64 mm 和 3.02 ± 0.69 mm，第一前磨牙的水平间隙最大，为 3.70 ± 0.68 mm，第二前磨牙为 3.19 ± 0.88 mm。与犬齿和前臼齿相比，门齿的水平间隙最小：结论：就JG而言，犬齿和前磨牙部位更适合即刻种植。相比之下，门牙部位应格外谨慎，必要时最好使用较窄的种植体。

期刊介绍： Journal of Prosthodontic Research is published 4 times annually, in January, April, July, and October, under supervision by the Editorial Board of Japan Prosthodontic Society, which selects all materials submitted for publication. Journal of Prosthodontic Research originated as an official journal of Japan Prosthodontic Society. It has recently developed a long-range plan to become the most prestigious Asian journal of dental research regarding all aspects of oral and occlusal rehabilitation, fixed/removable prosthodontics, oral implantology and applied oral biology and physiology. The Journal will cover all diagnostic and clinical management aspects necessary to reestablish subjective and objective harmonious oral aesthetics and function. The most-targeted topics: 1) Clinical Epidemiology and Prosthodontics 2) Fixed/Removable Prosthodontics 3) Oral Implantology 4) Prosthodontics-Related Biosciences (Regenerative Medicine, Bone Biology, Mechanobiology, Microbiology/Immunology) 5) Oral Physiology and Biomechanics (Masticating and Swallowing Function, Parafunction, e.g., bruxism) 6) Orofacial Pain and Temporomandibular Disorders (TMDs) 7) Adhesive Dentistry / Dental Materials / Aesthetic Dentistry 8) Maxillofacial Prosthodontics and Dysphagia Rehabilitation 9) Digital Dentistry Prosthodontic treatment may become necessary as a result of developmental or acquired disturbances in the orofacial region, of orofacial trauma, or of a variety of dental and oral diseases and orofacial pain conditions. Reviews, Original articles, technical procedure and case reports can be submitted. Letters to the Editor commenting on papers or any aspect of Journal of Prosthodontic Research are welcomed.
