Clinical Performance of Lithium Disilicate Veneer-Fixed Dental Prostheses for Incisor Tooth Replacement

23 participantsStarted 2011-10-03

Plain-language summary

This study evaluated a conservative treatment approach for replacing a missing upper front tooth (maxillary incisor). The treatment involved an all-ceramic, resin-bonded fixed dental prosthesis designed as a minimally invasive alternative to conventional bridges. The prostheses were fabricated from lithium disilicate glass-ceramic and were designed either with a single retainer (bonded to one adjacent tooth) or with two retainers (bonded to two adjacent teeth). All restorations were bonded using light-curing resin cement. The study assessed the clinical performance of these prostheses over a follow-up period of at least 12 months. Clinical evaluation included assessment of prosthesis integrity and function during the observation period.

Inclusion Criteria: * Patients with a missing maxillary incisor replaced with a veneer fixed dental prosthesis * Intact adjacent teeth suitable to serve as abutments * Adequate periodontal health and bone support of adjacent teeth * Age 18 years or older * Minimum of 12 months clinical follow-up available Exclusion Criteria: * Patients younger than 18 years * Adjacent teeth with extensive restorations, structural compromise, or inadequate enamel for bonding * Active periodontal disease affecting abutment teeth * Presence of parafunctional habits (e.g., bruxism or clenching) * Insufficient follow-up (\< 12 months) * Incomplete clinical records

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
