Alveolar bone grafts distal to the lower second molar

Abstract

The author suggests that for older patients (≥26 years) were there is the presence of partially exposed deep mesio-angular or horizontal impacted wisdom teeth, and which are associated with the radiographic appearance of bone loss to the distal surface of the lower second molar tooth, then alveolar bone grafting utilising Bio-Oss® and Bio-Gide® is an effective and stable treatment option to prevent development of periodontal pocketing in the area. The author advises for more guided and systematised study in this area.

The Effect of Alloplastic Bone Graft and Absorbable Gelatin Sponge in Prevention of Periodontal Defects on the Distal Aspect of Mandibular Second Molars, After Surgical Removal of Impacted Mandibular Third Molar: A Comparative Prospective Study

“…In this study the subjects in group I showed gradual increase in the bone level on the distal aspect of the mandibular second molar at 3rd and 6th months postoperatively. This was in accordance to the study by Coceancig [7] and Throndson and Sexton [26]. The increase in the bone level on the distal aspect of the mandibular second molar may be attributed to the presence of G-graft and its osteoconductive properties.…”

“…Surgical extraction of impacted third molars is the most commonly performed procedure in oral and maxillofacial surgical practice [1]. Studies have shown that surgical removal of impacted mandibular third molars results in intra-bony defects distal to the mandibular second molars [2][3][4].Various studies with numerous materials have been reported for prevention and management of this complication [5][6][7].…”

Prevention of Periodontal Pocket Formation after Mandibular Third Molar Extraction Using Dentin Autologous Graft: A Split Mouth Case Report

“…The development of a periodontal defect distal to the second molar is not predictable, and it is considered a complication difficult to treat and that will not heal spontaneously. There is consensus that the best way to prevent distal defects is the early extraction of third molars [ 32 – 35 ], but when this condition is not applicable, the risk of bone loss should be always taken in consideration. Richardson and Dodson revealed that after 2 years from the extraction of impacted third molars, the 43.3% of the patients showed a PPD of ~7 mm [ 29 ].…”

Effect of Xenograft on Alveolar Bone Healing Following Removal of Impacted Third Molar: A Randomized Controlled Clinical Trial

“…All of those symptoms affect the quality of the patient's life after the surgical procedure. (3)(4)(5)21) Many methods had been used to decrease the postoperative symptoms and improve the healing of the surgical sites. The present study aimed to investigate the effect Xenograft on the bone healing after surgical removal of mandibular third molar.…”

“…Once the periodontal defect and intrabony defect developed, they became difficult to treat through the traditional root planning, or simple local curettage and debridement (5) Therefore, it is beneficial to take into consideration that bone grafting of the resultant defects immediately following the surgical removal of impacted mandibular third molars as this will maintain the periodontal health through preserving the alveolar bone height. (4) Various studies with different materials have been used for prevention and management of these common complications.…”
