“…There were no occlusal problems in both the groups after 6 weeks and 6 months post-operatively. This is in accordance to study done by Bhatt et al 13 In the present study, the mobility of fracture fragment at the end of 1 st week of post-operative period in Group-I was found in 4 patients (44.4%), whereas there was no mobility of the fracture fragments after 6 weeks and 6 months postoperatively. In Group-II, there was no mobility of the fracture fragments post-operatively.…”

BACKGROUND Mandibular fracture treatment includes restoration of anatomic form and function with establishment of occlusion. Different methods are used to provide stable fixation like metallic compression plates, mini plates, locking plates, 3D plates and bioresorbable plates, etc.The present study compared the effectiveness of bioresorbable plates to the conventional titanium miniplates. MATERIALS AND METHODSNon-randomised controlled trial conducted on patients aged between 16 -56 years of either gender with clinical and radiographical evidence of mandibular fractures requiring open reduction and internal fixation, visiting dental department for the period of one year were enrolled for the study. They were intervened with either Bioresorbable Plates or Titanium Miniplates for the management of mandibular fractures under general anaesthesia. The patients were allotted in 2 groups. Group-I was treated with 2.5 mm Bioresorbable plates and screws; Group-II was treated with 2.0 mm Titanium miniplates and screws. Clinical and radiographic outcome parameters such as stability of occlusion, mobility of fracture fragments, need for intermaxillary fixation, wound healing, stability of fixation, displacement of fracture fragments and healing of fracture site were evaluated. RESULTSIn Group-I 6 patients showed unstable occlusion, 4 patients showed fracture mobility, 6 patients required intermaxillary fixation, whereas in Group-II only 3 patients had unstable occlusion, none of the patients showed fracture mobility (p < 0.05), only 3 patients required IMF during 1 st week post-operatively. There was no abnormality in wound healing/ soft tissue dehiscence and post-operative healing was satisfactory in both the groups. CONCLUSIONThe use of 2.0 mm titanium miniplates is a viable and better option as compared to bioresorbable plates for fixation of mandibular fractures. The stability of titanium plates is significantly higher than the bioresorbable plates for early function of mastication.

“…There is no difference in the rate of wound complication, subjective complaints, clinical or radiographic outcome in the use of absorbable vs stainless steel fixation (1)(2)(3)(4). Moreover, bioabsorbable material has some advantages compared with the titanium and other metals.…”

The aim of this study was to apply biomechanical analysis model to evaluate the effects of bioabsorbable internal fixation devices on maxillary Lefort Ι fracture. CT scan technology and the finite element software (ansys) were used to establish three-dimensional finite element models of five resorbable internal fixation devices in maxillary Lefort Ι fractures. We used the model to calculate the stress of the upper jaw and internal fixation. We further analyzed the stability of fixation under four occlusions. The fixation using two bioabsorbable plates was not stable. The zygomaticomaxillary pillars fixation is more stable than other fixations. The stability of fracture fixation was influenced with the molar occlusion. The current study developed a functional three-dimensional finite element model of bioabsorbable internal fixation and compared the stability of five fixation methods for maxillary Lefort Ι fractures. The results would facilitate the application of bioabsorbable materials in dental clinic.

“…7,8 These techniques produce extremely rigid and stable fixation, as the materials are stiffer than bone. As metal fixation has become widespread, however, limitations such as stress shielding of the bone, osteopenia, and interference with diagnostic imaging irradiation have become apparent.…”

A Simple and Reliable Method of Narrowing Genioplasty Using Biodegradable Screws

The T-osteotomy technique is widely performed to improve lower face aesthetics. During this narrowing genioplasty procedure, metal fixtures are required to rigidly fix the bone segments. Specifically, the use of biodegradable osteofixations has become a viable surgical option as more patients now have the desire to surreptitiously undergo aesthetic surgery. The present report describes a narrowing genioplasty procedure with the use of biodegradable screws only. When the T-osteotomy technique was performed to narrow the chin, the bone segments were first temporarily fixed with a 4-hole titanium plate and screws. Later during the operation, the plate and screws were replaced with 4 biodegradable screws with bicortical fixation. Completion of bone healing can be confirmed by follow-up radiographs taken 6 months after the surgery. Despite increasing demand for the use of absorbable materials in aesthetic surgeries, biodegradable fixation systems have not been widely used for aesthetic surgeries due to a perception of high cost, inconvenient manipulation, prolonged operative time, and suspicions on long-term stability. Our novel method of using only biodegradable screws allows such limitations to be easily overcome by surgeons.
