Brief Summary

The Intervention Will be All Ceramic Single-retainer Resin Bonded Fixed Partial Denture Using the Upper Canine as Abutment With Minimum Preparation on the Lingual Surface Within the Enamel Providing Maximum Area for the Retainer Bonding, to Replace the Upper Lateral Incisor and Will be Compared With the Control/Comparator Group Which is the All Ceramic Single-retainer RBFPD Using the Upper Central Incisor. The Participants in This Study Will be Recruited by the Researcher From the Clinic of Fixed Prosthodontics Department, Clinic of Orthodontics Department and Clinic of Diagnosis Department, Cairo University Without Any Financial or Non-financial Incentives.

Conditions

Survival, Prosthesis

Keywords

survival; upper lateral incisor; single retainer RBFPD; resin bonded fixed partial denture

Outcome Measures

Primary Outcomes (1)

• Survival rate in the term of retention and fracture

  The retention and fracture of the restoration of the two groups will be measured using the Modified United States Public Health Service (USPHS) criteria. Regarging retention (Alpha= no debonding, Charlie= debonding), while fracture will scored as (Alpha= no fracture, Bravo=Small chipping, but clinically acceptable, Charlie= Failure due to bulk fracture).

  12 months

Secondary Outcomes (1)

• Abutment tooth mobility and patient's satisfaction

  12 months

Interventions

all ceramic single-retainer resin bonded fixed partial denture PROCEDURE

The intervention will be all ceramic single-retainer RBFPD using the upper canine as abutment with minimum preparation on the lingual surface within the enamel providing maximum area for the retainer bonding, to replace the upper lateral incisor and will be compared with the control/comparator group which is the all ceramic single-retainer RBFPD using the upper central incisor.

Eligibility Criteria

• Age: 14 Years - 30 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17), Adult (18-64)

You may qualify if:

• Patients who have unilateral or bilateral missing upper lateral incisor and need to replace them with the following criteria:
• From 14-30 years old and be able to read and sign the informed consent document.
• physically and psychologically able to withstand conventional dental procedure
• Sound or minimally restored abutment with enough enamel surface area for bonding and no periodontal diseases.
• If the patient had previously undergone orthodontic treatment, a stabilization period of at least 3 months before impression taking.
• Good oral hygiene.
• Able to return for follow-up examinations and evaluation.
• No signs and symptoms of bruxism.

You may not qualify if:

• Pregnant women
• Increased overbite
• Bruxism, clenching or abnormal habits like nail or pencil biting that create occlusal forces
• Any developmental anomaly affecting the enamel of upper central incisor or canine
• Uncontrolled caries and periodontal disease and uncooperative patients. 6- Medically unfit for dental treatment and follow up.
