BioComp Implants in Anaplastology - Pilot Study

November 23, 2018 updated by: Maastricht University Medical Center

Safe and Easy Application of BioComp Implants for Prosthetic Reconstruction of Craniofacial Defects

At the department of Cranio-Maxillofacial Surgery, Maastricht University Medical Center (MUMC) the routine procedure after ablation of the nose, ear or eye is reconstruction with an episthesis. Retention can be achieved using adhesives, undercuts or bone implants. Implant based episthesis are now commonly used because of the good retention and episthesis stability. This results in a better patient quality of life.

Today we use machined surface implants in the craniofacial region of different brands. Each system has its own instruments and application method. To enhance the clinical usability, we are searching for one system for all extra-oral implant regions.

Furthermore, implant patients may be compromised by aging, diseases, smoking, medication and radiation therapy, which can affect the bone healing process. In these cases, implants are known to have higher failure rates compared to the application in healthy cases. Therefore implants with biomechanical surface modifications, such as the HAVD implants of BioComp, may have a positive effect on osseointegration, resulting in higher success rates in the compromised patient.

The aim of this pilot study is to collect information about the functionality and safety of a surface treated implant system (HAVD, BioComp) for episthetic reconstruction after ablative surgery in the nasal, orbital and auricular region for a potential future RCT.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame

Time Frame: one year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
