Background:Any injury to the face that affects the soft tissues, bones, skin, and other facial components is referred to as facial trauma. The present study was conducted to compare 2D miniplatesand 3D miniplates in mandibular symphysis fracture.Materials & Methods:60 cases of mandibular symphysisfractureof both genderswere divided into 2 groups. Each group had 30 patients. In the mandibular symphysis, group I patients received treatment with a 2.0-mm titanium 3D-miniplate, while group II patients received treatment with 2.0-mm titanium conventional miniplates. At one, three, and six months, parameters like mouth opening and sensory deficit/paresthesia were noted.Results: Group I had 19 males and 11 females and group II had 18 males and 12 females. Sensory deficit /paresthesia was seen in 3 in group I and 2 in group III at 1 month, 2 in group I and1 in group II at 3 months and 0 in group I and 1 in group II at 6 months. The difference was significant (P< 0.05). The mean mouth opening at 1 month was 24.2 mm and 24.4 mm in group I and II, at 3 months was 36.6 mm and 34.8 mm and at 6 months was 38.4 mm and 36.4 mm respectively. The difference was significant (P< 0.05).Conclusion: Traditional titanium miniplates can be substituted with 3D titanium miniplates. The technique offers a more reliable and efficient treatment option for mandibular symphyseal fractures than conventional miniplates.
