Ep. 809 - Mastering Large Composite Restorations

What if the crown you've been planning isn't always the best answer — and a well-executed direct composite could outperform it for decades?

Dr. John Gammichia is a 1995 graduate of the University of Florida College of Dentistry and a Fellow of the Academy of General Dentistry (FAGD) with over 31 years in private practice in Orlando, Florida. He has completed more than 1,500 hours of continuing education, including all five continuums and a special studies course at the L.D. Pankey Institute, and has published in Dental Economics, Dental Practice Reports, Dental Entrepreneur, New Dentist Magazine, and the Pankeygram. A former blogger for the Academy of General Dentistry and speaker at the Chicago Midwinter and AGD Annual Meeting, Dr. Gammichia has built a reputation for championing excellence in single-tooth, bread-and-butter dentistry.

In this episode, Dr. Gammichia makes a compelling case for direct composite restorations as a predictable, financially viable, and structurally conservative alternative to full coverage in a wide range of clinical scenarios — from multi-cusp fractures and cracked teeth to post-endodontic restorations and anterior cosmetic cases. He walks through his complete clinical armamentarium, shares 30-plus years of real-world longevity data from his own recall patients, and explains how thoughtful material selection, technique, and case philosophy have made large composite buildups the cornerstone of his practice. This conversation challenges deeply held restorative assumptions while offering actionable clinical guidance that can be applied immediately.

• Episode Highlights:
• Large direct composite restorations on multi-cusp fractures can be clinically predictable and financially competitive with crowns. When factoring in lab fees and chair time, two direct composite restorations completed in an hour can generate comparable or higher hourly production than a single crown appointment — making efficiency with composites a legitimate practice-building strategy.
• Adhesive systems have advanced to the point where posts are rarely necessary even in heavily broken-down posterior teeth. A selective etch technique using a thick, antimicrobial etchant combined with a self-etching primer and bond provides reliable retention without the need for intracoronal post placement in the vast majority of molar cases.
• Curing light quality and testing are critical — and often overlooked — variables in composite longevity. A laser-based curing light using a one-second cure cycle through a focused, highly collimated beam has shown excellent results in deep preparations, provided the composite contains a camphoroquinone photoinitiator. Lights should be tested regularly to ensure consistent output.
• For cracked teeth or post-endodontic restorations without pre-existing full coverage, a fiber-reinforced mesh splinting material placed perpendicular to the fracture line beneath a composite restoration can provide meaningful structural reinforcement. The speaker reserves crown preparation for cases where the tooth already had a crown that required removal — not as a routine post-endodontic default.
• Deep caries management with incomplete caries removal, glass ionomer liner, silver diamine fluoride application to arrest the lesion, and either a sandwich technique or direct composite placement over the liner offers a pulp-preserving approach for young patients with large lesions. This sequence prioritizes pulp vitality and avoids root canal therapy while delivering a durable, well-sealed restoration.

Perfect for: General dentists at any career stage looking to expand their direct restorative skill set, dental residents rethinking default crown preparations, and any clinician interested in the clinical and financial case for composite-first treatment planning.

If you've ever hesitated before presenting a direct composite on a heavily broken-down tooth, this episode will give you both the clinical rationale and the confidence to reconsider.
