Posterior sector rehabilitation with endodontics and build-up:
stability and predictability with Kiyomi Dental
Rehabilitation of the posterior sector represents one of the greatest challenges in restorative dentistry, especially when a tooth must serve as an abutment in a fixed prosthesis. In this clinical case, Dr. Francisco Monzó addresses the restoration of an edentulous area in the upper maxilla (tooth 26), using tooth 27 as the key abutment for a 25–26–27 bridge, through a combination of endodontic treatment, fiber post placement, and core build-up.
Diagnosis and planning
The patient presented with a missing tooth in position 26, requiring both functional and aesthetic rehabilitation. Tooth 27, structurally compromised, required prior endodontic treatment to ensure its viability as a prosthetic abutment. The treatment plan focused on achieving a solid foundation, prioritizing overall stability through a proper ferrule effect and a reliable core reconstruction.
Step-by-step clinical procedure
Under rubber dam isolation, endodontic treatment of tooth 27 was performed. Once completed, the palatal canal was prepared, leaving adequate space for the cementation of a glass fiber post. This step is essential to reinforce the internal tooth structure and improve force distribution.
Next, the adhesive protocol was carried out using Kiyomi Dental materials, designed to simplify clinical workflows without compromising results:
- Selective enamel etching with K-Etch 37%, a highly effective phosphoric acid that ensures optimal micromechanical retention on peripheral enamel.
- Application of K-Bond Universal+, a universal adhesive known for its excellent wettability, high bond strength, and compatibility with multiple techniques (total-etch, selective-etch, or self-etch).
- Core build-up using Dual Cem Core, a dual-cure composite with high mechanical strength, ideal for build-ups in endodontically treated teeth.
Advantages of Kiyomi Dental materials
The combined use of these products enables a cohesive, optimized, and highly predictable system. Compared to other solutions on the market, Kiyomi stands out by offering materials that balance ease of use with clinical performance:
- K-Etch 37% provides uniform and controlled etching, facilitating durable adhesion without over-etching.
- K-Bond Universal+ delivers versatility and reliability, reducing technique sensitivity and enhancing restoration longevity.
- Dual Cem Core combines high compressive strength with easy handling, allowing stable reconstructions even in cases of significant structural loss.
Outcome and conclusion
The result is a solid core build-up that optimizes the surrounding ferrule effect, significantly improving the tooth’s resistance to functional loads. This stability is essential to ensure long-term success in posterior prosthetic rehabilitation.
This clinical case demonstrates how, through proper planning and the use of appropriate materials, it is possible to restore function and durability to compromised teeth. At Kiyomi Dental, the goal is clear: to provide solutions that enable clinicians to achieve excellence in a simple, reliable, and predictable way.
