Cross bite - Prosthodontics approach

Patient came in our practice and asked for correction of his bite. He said that when he was younger his bite was edge to edge but through the years his lower jaw slide forward. He felt uncomfortable with cross bite, and he had problems with chewing and lateral movement of the jaw, he felt like his lower jaw is without any support. After intraoral and RTG examination we found old fillings, dental wear, cavities and old metalceramic bridges in lower and upper left TKS. We diagnosed this case as loss of bite which progresses in cross bite. Our choice of treatment was full mouth reconstruction by increasing VDO and reposition of TMJ in the most upper and posterior position. After exercising with the jig and the relaxation of lateral pterygoid muscle the registration of the bite was taken in CR. In this position we designed temporary crowns from PMMA and we made follow up of the new bite and VDO for three months. Patient felt well. Hi didn’t have any problems with the reconstruction, on the contrary he felt stable and comfortable. Lateral movements are canine guided and the chewing is easier. After the adaptation period we remade the reconstruction with metal ceramic crowns and bridges. Patient wears night guard.
