[Research on the relation between the biting force with complete denture and compression of the mandibular denture bearing mucosa].
This experiment was designed to study the relation between the biting force and compression mucosal recovery and recovering time of the denture bearing mucosa with ten edentulous patients by the occlusometer and the photoelectric movement transducer. The results showed that the favourable threshold of biting force for denture bearing mucosa was 1.3 kg in anterior tooth region and 2.5 kg in molar region, up to 30 minutes after removal of biting force, the mucosal thickness was still 0.20 mm in anterior tooth region and 0.11 mm in molar region. According to these characteristics of the denture bearing mucosal compression and recovery, masticatory force of the complete dentures should be limited below above mentioned threshold.
