10 I I clinical_ partial-coverage restorations _In spite of significant advances in the ability to provide predictable, adhesively retained partial- coverage restorations, full-coverage restorations continuetobethemainstayofdentaltreatment.The vastmajorityofindirectrestorationsprovidedforpa- tients, both anterior and posterior, are full-coverage crowns. This is perhaps not surprising, given that preparing teeth for partial-coverage restorations is more technically demanding and potentially more challenging to facilitate an esthetic outcome, not to mention the added challenges to a traditional work- flowwhenarestorationistobeadhesivelycemented. While bonded partial-coverage restorations present different challenges when compared to conventionallycementedfull-coveragerestorations, many of these obstacles have been significantly reduced in recent years. The development of novel isolation devices and significant advances in hemo- static agents and dental lasers have made obtaining appropriate isolation for bonding much easier. Vast improvements in resin cement properties and adhe- siveshavemaderestorationdeliveryandsubsequent clean up easier and less technique sensitive than ever before. Even more importantly, there now exist highly estheticceramics,suchasIPSEmpressandIPSe.max (Ivoclar Vivadent, Schaan, Liechtenstein) that can mimic natural dentition, be quickly and predictably fabricated, and have a proven track record of clinical success.1, 2 There are a number of advantages to bonded partial-coveragerestorationsoverfull-coverageres- torations. These largely center around the fact that partial-coverage restorations preserve significantly more tooth structure than full-coverage restora- tions. Multiple studies have shown partial-coverage all-ceramic restorations to be significantly more conservative of tooth structure, even when com- pared to a cast gold restoration.3–5 Full-coveragerestorationshavelongbeenassoci- atedwithanincreasedriskforpulpalcomplications4 , which could be significantly avoided with partial- CAD/CAM 3_2016 Leveraging modern technology and materials to provide better outcomes for our patients Author_Clint D.
