Evaluating patient experiences with implant-supported crowns versus removable dentures
Patient Perception and Oral Function of Implant-supported Restorations Replacing Posterior Teeth
NA · University of Copenhagen · NCT06463405
This study is testing how people feel about their chewing and overall quality of life when they get implant-supported crowns instead of removable dentures or no treatment at all.

What this trial studies
This study aims to assess how patients perceive their oral function and quality of life when posterior teeth are replaced with implant-supported crowns compared to removable partial dentures (RDPs) or no treatment. It will also develop and validate new 3D digital methods for measuring occlusal contacts and analyze their relationship with masticatory ability. Additionally, the study will compare the biological and technical outcomes of splinted versus non-splinted implant-supported crowns over time. Participants will include partially edentulous individuals in good health who require fixed implant-supported crowns.
Who should consider this trial
Good fit: Ideal candidates are partially edentulous individuals with missing posterior teeth who are in good health and require fixed implant-supported crowns.
Not a fit: Patients with untreated periodontitis, significant systemic health issues, or those requiring major bone augmentation may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could enhance patient satisfaction and oral function by identifying the most effective treatment for replacing missing posterior teeth.
How similar studies have performed: Other studies have shown promising results with implant-supported crowns, but this specific approach using new 3D methods is relatively novel.
Eligibility criteria
Show full inclusion / exclusion criteria
Inclusion Criteria: * Partially edentulous subjects with missing posterior teeth (Kennedy class I or class II) in the upper or lower jaw, in need for fixed implant-supported crowns to replace the missing teeth are offered to be enrolled if they fulfill the following inclusion criteria. The participants must be in good health and with no contraindications for undergoing dento-alveolar surgery. Exclusion Criteria: * Untreated or active, progressive periodontitis * Intake of (high dose) antiresorptive medicine or earlier medication related osteonecrosis of the jaw * Therapeutic radiation to the head and neck * Uncontrolled diabetes or systemic corticosteroids * Heavy smoking (\>20 cigarettes/day) * An inability to open the mouth wide enough to place implants * Decayed or unrestored anterior/premolar teeth * Need for major bone augmentation (e.g., bone block graft, extensive augmentations with second operation for implant insertion) * \< 8 mm bone height to the alveolar nerve or sinus maxillaris * Parafunctional habits or untreated temporomandibular dysfunctions or orofacial pain * Unable to cooperate or too ill to complete the experiment * Lack of signed informed consent
