Influence of Length of Occlusal Support on Masticatory Function of Free‐End Removable Partial Dentures: Short‐Term Adaptation

Abstract

After a 1-week adaptation period to free-end RPDs with occlusal support lengths reduced to the premolars, participants were able to achieve adequate masticatory function.

Effects of removable dental prostheses on masticatory performance of subjects with shortened dental arches: A systematic review

“…19 In 4 studies X 50 was determined after a given number of chewing strokes; one study determined D 50 , which is equivalent to X 50 until swallowing. 22 Three studies 22,24,25 also reported on chewing frequency and 2 studies 23,26 on maximum bite force.…”

“…24 The study of Sánchez-Ayala et al 25 showed a more or less linear effect of decreasing chewing frequency with increasing number of artificial teeth added on the RDP, in that study with an opposing maxillary complete denture.…”

“…A c c e p t e d M a n u s c r i p t 9 studies (ranging from -7 to +1%), 22,25 however relatively large in another (-11 to +57%). 24 The study of Sánchez-Ayala et al 25 showed a more or less linear effect of decreasing chewing frequency with increasing number of artificial teeth added on the RDP, in that study with an opposing maxillary complete denture.…”

“…28 Three papers reported additionally chewing frequency data. Chewing frequencies were expressed as chewing strokes per second, 22 chewing stokes per minute, 25 or time needed for 20 chewing strokes. 24 If applicable the outcomes were converted to chewing strokes per second (Table 4).…”

“…A c c e p t e d M a n u s c r i p t 11 example the studies of Bessadet et al 22 and Aras et al 23 reported data based on regular RDP wearers with and without their RDP in situ, whilst the outcomes from the Sánchez-Ayala et al 25 and Shoi et al 28 studies were based on experimental RDPs in ESDA subjects. The chewing instructions to the participants varied form habitual chewing to unilateral chewing.…”
