Physiology and Terminology of Removable Partial Dentures (GTSL)

Oral Health and AgingPage 1

Oral weakness in the elderly, defined by the Japan Dental Association, involves a decline in oral function, mental state, and physical capacity. This condition is closely linked to sarcopenia, malnutrition, and cognitive decline, highlighting the critical role of maintaining oral health for longevity.

Impact of Tooth LossPage 1

Untreated tooth loss leads to detrimental effects, including dental migration, supra-eruption, reduced chewing efficiency, TMJ disorders, speech impairment, and diminished nutritional intake. These factors contribute to systemic health issues and physical frailty.

Prosthetic Dentistry ConceptsPage 2

Removable Partial Dentures (GTSL) aim to restore function, aesthetics, and phonetics while maintaining the health of oral tissues. Essential terminology includes Abutment (supporting teeth), Retainers (for stability), and concepts of Retention, Stability, and Support.

Metal vs. Acrylic Denture BasesPage 3

Metal-based dentures (GTSKL) offer superior rigidity, thermal conductivity, and structural stability, making them a preferred choice for long-term use. Acrylic dentures are utilized primarily for interim, transitional, or treatment purposes, as they are easier to reline, adjust, and cost-effective, despite having lower mechanical strength and higher porosity.

Clinical IndicationsPage 3

GTSL is indicated when fixed prosthodontics are contraindicated due to long span edentulism, lack of posterior abutments, or severe bone loss. Treatment dentures are specifically used for healing, medication delivery, or vertical dimension (DVO) correction.
