Using the neutral zone technique for better denture cleansing

Successful rehabilitation treatment such as complete dentures depends on the construction stage and denture maintenance following insertion. Denture hygiene maintenance is important to decrease the possibility of denture stomatitis; this can occur when plaque accumulates on the denture and is influenced by the denture's polished surface shape. Construction of polished surfaces of complete dentures can be done with the neutral zone technique to ensure better denture stability and good cleansing. This technique is performed with functional movement or the phonetic method. A 74-year-old female patient presented to Dental Teaching Hospital, Faculty of Dentistry, Universitas Indonesia, for obtaining complete dentures so that she could have a better masticatory function. She lost all her teeth and wore a loose partial denture. The neutral zone technique was used to fabricate a good polished surface shape. The impression was made after determining the occlusal vertical dimension of the patient using the phonetic method. The neutral zone technique can produce a complete denture with a good polished surface shape that enables the easy removal of accumulated plaque.
