Abstract

Bone harvesting from the anterior nasal spine (ANS) is frequently used to correct peri-implant bone defects, particularly during implant placement in the anterior maxilla. However, many clinicians are concerned about the postoperative effect of removing the ANS on the nasal outline, as the ANS is integral to supporting the nose. This study aimed to describe the technique of ANS bone grafting and to investigate postoperative effects of bone harvesting from the ANS on the overall nasal shape. Fifteen patients with single maxillary first incisal rehabilitation using dental implant were enrolled in this prospective clinical study. Simply by extending the subperiosteal dissection in the same surgical field without additional local anesthesia, a bone block of about 0.25-0.5 ml could be harvested from the ANS. Nose width (NW), nasolabial angle (NLA), and nasal tip depth (NTD) were measured and analyzed by lateral and frontal photographs taken preoperatively (T0), and at postoperative 1 week (T1), 3 months (T2), and 6 months (T3). Postoperative complications were also recorded. A significant increase in NW and decrease in both NLA and NTD were found at T1 (P < 0.05). At T3, NW, NLA and NTD returned to preoperative measurements at T0 wi...Continue Reading

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

Aphasia

Aphasia affects the ability to process language, including formulation and comprehension of language and speech, as well as the ability to read or write. Here is the latest research on aphasia.
