“…In cases where the underlying bony support is atrophied, widening of nose width and collapsing of nasal tip could be secondarily manifested. [9] In this article, the mesiodens in premaxilla was under the ANS whose morphology would be damaged when removing the mass bone quantity, while less bone quantity reduction may not expose the tooth. Using the trapdoor method could not only preserve the appearance of ANS, but also could assure the vascularity and viability of the bony window, which promoted quick recovery and decrease possibility of infection due to blood supply.…”

“…[1,6] Moreover, ANS plays an important role as a bony structure supporting the columella and nasal tip while maintaining the individual nasolabial angle (NLA). [9] Piezosurgery, as a promising, meticulous and soft tissue-sparing system, has proven to be an effective tool for cutting bone without encountering necrosis from overheating and damaging soft tissues. Its atraumatic manipulation of tissues and precision in surgery are widely accepted by oral and maxillofacial surgeons.…”

The aim of this study was to introduce a novel method of mesiodens extraction using a vascularized pedicled bone flap by piezosurgery and to compare the differences between a computer-aided design surgical guide template and free-hand operation.A total of 8 patients with mesiodens, 4 with a surgical guide (group I), and 4 without it (group II) were included in the study. The surgical design was to construct a trapdoor pedicle on the superior mucoperiosteal attachment with application of piezosurgery. The bone lid was repositioned after mesiodens extraction. Group I patients underwent surgeries based on the preoperative planning with surgical guide templates, while group II patients underwent free-hand operation. The outcome variables were success rate, intraoperative time, anterior nasal spine (ANS) position, changes of nasolabial angle (NLA), and major complications. Data from the 2 groups were compared by SPSS 17.0, using Wilcoxon test.The operative time was significantly shorter in group I patients. All the mesiodentes were extracted successfully and no obvious differences of preoperative and postoperative ANS position and NLA value were found in both groups. The patients were all recovered uneventfully.Surgical guide templates can enhance clinical accuracy and reduce operative time by facilitating accurate osteotomies.

“…The chin bone and mandibular body bone were harvested when the bone defects were present in those areas. ANS is a useful site for a small amount of bone graft [ 17 ]. When bone defects are less than 1 cm in the anterior maxilla, single-side simple vertical incision is enough to expose ANS.…”

BackgroundImplant surgery has become popular with the advance of surgical techniques such as sinus lifting, guided bone regeneration, and block bone graft. However, there were no data about the frequency of bone graft during implant surgery. The purpose of this study was to report the frequency and types of bone graft depending on dental implant patients’ profile to complement the database regarding implant surgery.MethodsThe implant operations had been performed from January 2006 to October 2014. The upper and lower jaws were divided into six sextants. A total of 792 sextants were included in this study. Patient information including sex, age, sites, bone graft, and types of bone were investigated.ResultsA total of 1512 implants had been placed. Male and female sextants were 421 and 371, respectively (M:F = 1:0.88). Average age was 54.3 (ranging from 20 to 88 years old). Implants were placed in the posterior maxilla (322 sextants, 40.7 %), posterior mandible (286 sextants, 36.1 %), anterior maxilla (127 sextants, 16.1 %), and anterior mandible (57 sextants, 7.2 %). Bone graft was performed in 50.3 % of the sextants. Among the bone grafted sites, sinus lifting with lateral approach (22.1 %) and guided bone regeneration (22.7 %) were performed most frequently.ConclusionsBone graft in implant surgery was necessary to augment defects. More than half of the sextants needed bone graft for implant installation.

BackgroundProvide a review of alternative intraoral donor sites to the chin and body-ramus of the mandible that bring fewer complications and that may be used to regenerate small and medium defects.Material and MethodsA review was conducted using the search engine PUBMED and looking manually into scientific journals.ResultsFrom the 35 articles included, 6 corresponded to the coronoids, 3 corresponded to the zygomatic body, 5 corresponded to the anterior maxillary sinus wall, 3 corresponded to the zygomatic alveolar process, 2 corresponded to the incisive fossa, 2 corresponded to the anterior nasal spine, 2 corresponded to the palatal region, 5 corresponded to the tuberosity, and 7 corresponded to the palatal and mandibular tori.ConclusionsAlthough there are few complications described when using alternative intraoral donor sites, the main problem with these types of grafts is their scarce bone volume, with only the zygomatic body, anterior sinus wall, and palate sites being able to be used in medium defects. More clinical trials are necessary in order to evaluate the behavior of the alternative donor sites over time. Key words:Grafting, autologous bone, autografts, mandible, maxilla, palate hard, zygoma.

Postoperative effects of anterior nasal spine bone harvesting on overall nasal shape

Abstract: The ANS could be an effective and easily accessible intraoral source for autologous bone. Despite acute soft tissue swelling, the net postoperative effects of removing the ANS on the overall nasal shape, including on nasal tip collapse or widening of the nose base, were negligible.
