Prosthodontics Revision Notes

💡 Primary = Alginate/Impression compound. Secondary = ZOE/Elastomers. Border molding sequence: Posterobuccal → Distobuccal → Anterobuccal.

💡 VDO - VDR = Freeway space (2-4mm). Gothic arch tracing = intraoral. Facebow transfers = arbitrary (most common) vs kinematic.

💡 Balanced occlusion = complete dentures. Mutually protected = natural dentition. Hanau's quint = CG/CI/CP/OPP/CC. Christensen phenomenon.

💡 Class I = bilateral posterior. Class II = unilateral posterior. Class III = unilateral bounded. Class IV = bilateral anterior (NO modification). Applegate's rules.

💡 Akers clasp = most common. RPI system = Class I/II. Major connector: Palatal strap (most common maxilla), Lingual bar (most common mandible). 4mm floor of mouth depth needed for lingual bar.

💡 Ante's law = root surface of abutments ≥ pontics. Sanitary pontic = posterior mandible. Modified ridge lap = posterior maxilla = most hygienic fixed pontic.

💡 Branemark = osseointegration pioneer. Implant success criteria: <1mm bone loss in 1st year, <0.2mm/year after. Implant surface: SLA > machined. Wait 3-6 months for osseointegration.

💡 Surgical obturator → Interim obturator → Definitive obturator. Aramany classification for maxillectomy defects.

💡 Most accurate = Polyvinyl siloxane (addition silicone). Alginate = irreversible hydrocolloid. Agar = reversible hydrocolloid. Elastomeric ranking: Polysulfide (least) < Condensation silicone < Polyether < Addition silicone (most accurate).

💡 Gagging = posterior palatal seal too far back. Clicking = excessive VDO. Burning = allergic to monomer. Epulis fissuratum = ill-fitting denture flange.
