“…The use of titanium bone plates has been described and appreciated by several authors. According to those studies [14][15][16][17] fractures treated with titanium bone plates and screws had less post-operative infection rate compared to stainless steel, similarly in our study, in Group II patients had infection at suture and wound dehiscence in 2 patients. Mandible fractures if it is a complex type, there can be a tendency for infection when there is breach in soft tissue cover, poor patient compliance in oral hygiene maintenance and also as a result of inadequate rigidity and immobilization.…”

“…In our study, occlusions of the patients were checked postoperatively and during follow ups had no major occlusal discrepancies. [2,17,18] Minor occlusal disturbances if present can be corrected using guiding elastics. In two of our patients, wound dehiscence was seen due to inadequate tissue available or closure of wound under tension during suturing which resulted in tension along the suture line which required resuturing later, all the patients were kept on antibiotic therapy and regular follow-up was done.…”

Introduction: Rigid internal fixation using Champy's miniplates is one of the commonly used treatment modalities to treat mandibular anterior fractures. The drawbacks of these methods have led to the evolution of 3-dimensional (3-D) miniplates. This study was designed to compare the efficacy of single 3-D miniplates over Champy's 2 miniplates in mandibular symphysis and parasymphysis fractures. Materials and Methods: 20 patients with anterior mandibular fractures were randomly were divided into 2 groups, wherein single 3-D plates were placed in Groups I and 2 miniplates in Group II. The efficacy of 3-D miniplates over Champy's miniplates was evaluated in terms of the following parameters: Operating duration, occlusal discrepancy, infection, mobility of fracture segment, wound dehiscence, neurological function. Results: The mean operation duration for Group I was less compared to Group II (statistically significant), wound dehiscence were present in 2 cases in Group II, neurological deficit in one case in-Group II (statistically insignificant). Conclusion:The results of the study confirms that single plate fixation of mandibular anterior fractures with 3-D titanium miniplates system is a good alternative to Champy's 2 miniplates system as it provides good stability, requires less intraoperative time and carries lower rates of infection compared to the regular miniplate systems.

Purpose This prospective study was conducted to evaluate the efficacy of stainless steel single linear miniplate with rectangular grid plate in the treatment of mandibular angle fractures. Methods This study included 30 patients who were allocated randomly into two groups of each. Group 1 patients were treated with single 2 mm 9 4 hole linear stainless steel miniplate and group 2 patients with 2 mm 9 4 hole rectangular grid plate. Patients were evaluated for fracture stability, occlusion, mouth opening, and complications at 1st week, 1 and 3 months post operatively. Results There were no significant differences between the two groups with respective variables statistically. In group 1 20 % (n = 3) had mild occlussal derangement 6.66 % (n = 1) patient had deranged occlusion at 1 week post operatively and 13.3 % (n = 2) had mild derangement at 1 month post operatively. In group 2 6.66 % (n = 1) had mild derangement at 1 week postoperatively. 20 % (n = 3) had limited mouth opening at 1 week in group 1 and 13.3 % (n = 2) in group 2. All patients in both groups achieved adequate mouth opening by the end of 3 month. None of the patients in both groups had plate fracture, screw loosening, non union or mal-union. Conclusion Within the limits of the study, use of rectangular grid plates for fixation of mandibular angle fractures was reliable with low complication rates, easy adaptation and an effective alternative to conventional miniplates. Further clinical studies with larger sample size can derive a more comprehensive conclusion.

“…They found IAN neurosensory disturbances were unchanged or improved immediately after treatment in most patients. In our cases temporary paresthesia was noted to be present in 2 patients in group II (Case No:12 & 17)  M.Witten berg et al used 3-D plates in mandibular fractures and they noticed that the use of 3-D plates easier to place intra orally [15]. Because of closed quadrangular geometric shape and ease of contouring and adapting to bony fragments it provide good stabilization in three dimensions].…”

ARTICLE INFO ABSTRACTPurpose: To compare and evaluate 3-dimensional (3D) and conventional 4-hole miniplates fixation in the management of mandibular fractures. Materials and Methods:In 20 randomly selected patients who sustained mandibular fractures were selected for this study. Of the 20 cases, in 10 cases fractured fragments were stabilized using 2.0mm 3-Dimensional miniplates and in remaining 10 cases the fractured fragments were fixed with conventional 2.0mm miniplates. Post operatively cases were assessed clinically and radiographically at immediate post op, 1month and 3months.Results: This study suggests that fixation of mandibular fracture with 3D Plates provide three dimensional stability and carries low morbidity and infection rates. The only probable limitation of these plates may be excessive implant material due to the extra vertical bars incorporated for countering the torque forces and in cases where the fracture line passing through the mental foramina region. Conclusion:The 3D plate was found to be standard in Profile, strong yet malleable, facilitating reduction and stabilization at both the Superior and inferior borders giving three dimensional stability at fracture site. They seem to be an easy to use alternative to conventional miniplates. But the small sample size and limited follow up could be considered as the limitations of our study.
