Removable Partial Denture / GTSL Design?
Good afternoon, please explain about the design of GTSL class 1 and class 4 and about the grip. Please help, Thank you 🙏
Dentures are tools used to replace missing teeth. A removable partial denture / GTSL is a denture that can be used to replace one or several teeth, either in the upper or lower jaw, which can be opened and attached (detached) by the patient.
To determine the GTSL design, there is a classification, namely the applegate-kennedy classification, namely:
Class I: toothless areas covering the back of the remaining teeth on both sides of the jaw, a 2-sided GTSL with base extension distally used
Class II: toothless area covering the back of the remaining teeth but on one side of the jaw only, bilateral GTSL with base extension distally used
Class III: toothless area between other teeth but 2 neighboring teeth unable to provide support for the denture as a whole, used bilateral design GTSL
Class IV: toothless areas on the front and teeth that still cross the midline, fixed dentures are used if neighboring teeth are still strong, bilateral design GTSL with tooth / tissue / combination support
Class V: toothless area between the teeth where the front neighbor teeth cannot be used as a support and cannot withstand chewing power, a bilateral design GTSL is used, free-tipped base at the front
Class VI: toothless area between the teeth with strong neighboring teeth, used fixed or removable 1-sided dentures
For more details or in detail, you can ask the dentist directly or from journals and textbooks.
Hope it can help you,
