Purentakyky

Purentakyky is a Finnish term used in dentistry to describe the functional capacity of the masticatory system to bite and chew. It covers both the strength of the bite (bite force) and the efficiency with which food is crushed and processed, reflecting overall oral function.

Measurement and assessment methods include estimating maximum voluntary bite force (MVBF) with a bite force transducer, usually placed behind the molars, and reporting the force in newtons. Additional evaluations examine masticatory performance through standardized test foods or color-changing chews to gauge chewing efficiency, as well as electromyographic (EMG) activity to assess facial muscle coordination. Occlusal contact area and force distribution are also considered.

Factors influencing purentakyky are diverse. Dental status is central: the number and condition of natural teeth, denture fit and stability, and the presence of dental implants or prostheses. Occlusion, temporomandibular joint health, and neuromuscular control affect function. Age, sex, general health, nutrition, tooth wear, pain, and parafunctional habits such as bruxism can modify purentakyky.

Clinical relevance is high for nutrition, comfort, and quality of life, particularly in older adults or patients undergoing restorative treatment. Reduced purentakyky is common after tooth loss or poorly fitting dentures, and it may be improved through appropriate prosthodontic rehabilitation, occlusal adjustments, implant-supported restorations, or targeted orofacial therapy.

Purentakyky is commonly discussed in prosthodontics, gerodontology, and dental biomechanics as a practical measure of functional jaw performance and treatment outcomes.
