Tapered, Sand-Blasted, Large-Grit, and Acid-Etched Surfaced Internal Dental Implant in the Diverse Pathologic Jaw

Abstract

Purpose: The treatment of pathologic lesions in jaws either through conservative or radical approaches, frequently leads to a loss of teeth. As a result, patients will experience diminished masticatory and phonetic function as well as esthetic deficits. In this manuscript, we report multiple cases of successful implant rehabilitation after the conservative treatment of pathologic lesions in jaws utilizing allogeneic bone grafts and the installation of implant fixtures. Materials and Methods: In this study, we examined 8 patients with 8 different kinds of pathologic lesions in their jaws, who were treated with a conservative approach and rehabilitated with bone grafts and implant installations using internal dental implant type with tapered, sand-blasted, large-grit, acid-etched surfaces. Marginal bone loss was analyzed through radiograms, and the implant survival rates and graft outcome evaluations were recorded. Results: No significant difference was found in the mean marginal bone loss throughout the follow-up period. The survival rate of the implant and the success rate of graft were recorded as 100%. Conclusions: The results of this study suggest that conservative surgical management for pathologic lesions based on the understanding of the pathologies can be helpful for successful oral rehabilitation. In bone grafting, it is necessary to determine an appropriate timing and method considering the risk of recurrence and the vascularity of the recipient site. For subsequent implant placement, selecting an implant system suitable for the site of placement and placing it within 3 to 6 months after bone grafting can help the long-term maintenance of the grafted bone and dental implant.

Appropriate Total Rehabilitation in the Bilateral Maxillectomy Defected Diabetic Patient Secondary to Aggressive Aspergillosis

“…In case of favorable vascularity in the recipient site and low risk of recurrence, bone graft can be conducted three to six months following lesion removal. 23 In this case, with the advantage of the palatal flap preservation, the remaining tissues at the bone graft recipient site are well-vascularized by the greater palatine artery. From endoscope examination, the recurrence rate was low, and complete remission was achieved after removal of the early recurrence.…”

“…For selection of dental implants, a tapered, sand-blasted, large-grit, and acid-etched surfaced internal dental implant has shown benefit in pathologic jaws and immunocompromised patients. 23,24 With the implant-bar-supported removable denture, good retention with minimal pressure to the tissue can be maintained with good hygiene. In addition, using the removable denture, the border of the post-operative area can be inspected for any signs of recurrence.…”

“…In a previous study, the use of allogeneic and xenogeneic particulate bone grafts in diverse pathologic jaws has shown successful outcomes with good integration to the remaining bone and implant. 23 For determining the appropriate timing of bone graft, when the recipient site has poor vascularity and recurrence is high, the bone graft should be performed after long-term follow-up, with a minimum 1.5 years. In case of favorable vascularity in the recipient site and low risk of recurrence, bone graft can be conducted three to six months following lesion removal.…”

“…Bone deficits caused by maxillectomy can be reconstructed with bone graft and implants. In a previous study, the use of allogeneic and xenogeneic particulate bone grafts in diverse pathologic jaws has shown successful outcomes with good integration to the remaining bone and implant 23 . For determining the appropriate timing of bone graft, when the recipient site has poor vascularity and recurrence is high, the bone graft should be performed after long-term follow-up, with a minimum 1.5 years.…”

Guidance and rationale for the immediate implant placement in the maxillary molar

“…Tapered SLA dental implants such as Straumann, Shinhung Implant System, and Anyone by Megagen also provide self-cutting effects, which are favorable in preserving crestal bone level especially in immediate implant placement 33 . The high success rate of these implants was shown in rehabilitation of diverse pathologies of the jaw and in well-integrated grafted bone following management of oroantral fistula and odontogenic maxillary sinusitis 34 , 35 .…”
