Lithium Disilicate Glass-ceramic Versus Hybrid Ceramic Superstructure Materials on Implant Stability (RCT)
Prosthesis Survival
About this trial
This is an interventional prevention trial for Prosthesis Survival focused on measuring implant supported restorations, IPS Emax (lithium disilicate glass-ceramic), Vita Enamic (hybrid dental ceramic), implant survival, peri-implant tissue response
Eligibility Criteria
Inclusion Criteria:
Patients > 18 yrs. Patients with missing teeth in the maxillary premolar region. Absence of any pathological condition in the recipient site.
Stabilization phase will be performed including:
- Scaling
- Debridement.
- Elimination of all carious cavities and root canal treatment if needed.
- Elimination of over-hanging restoration. Systemic condition of the subjects was evaluated according to dental modification of the Cornell medical index (Kerr and Millard 1966).
Patients who are cooperative, motivated, and hygiene conscious. Patients should have adequate ridge width (>5mm).
Exclusion Criteria:
Patients unable to undergo minor surgical procedure. Patients with history of drug abuse or metabolic drugs. Patients with history of psychiatric disorder. Patients with insufficient bone. Patients with insufficient vertical inter-arch space, upon centric occlusion, to accommodate the available restorative components.
Patients with any systemic condition that may contraindicate implant therapy. Patients that may have any habits that may jeopardize the osseo-integration process, such as heavy smoking and alcoholism.
Patients with para-functional habits that produce overload on the implant such as bruxism and clenching.

Active Comparator
Hybrid superstructure
Ceramic superstructure
Vita Enamic is a hybrid ceramic, consisting of composite and ceramic. The ceramic; compatible and high aesthetics while the composite; resilient material with low modulus of elasticity which will absorb stress and therefore decrease load on bone and eventually decrease crestal bone loss
IPS Emax, is the mostly used ceramic superstructures in implant supported restorations.
