Summary
This study shows that the denture conversion protocol for immediately loaded acrylic resin complete arch fixed implant-supported prostheses (CAFIP) has a high survival rate (98% for implants, 94% for prostheses). This evidence-based technique is predictable for immediate implant loading.
Area of Science:
- Dental Implantology
- Prosthodontics
- Materials Science in Dentistry
Background:
- Immediate loading of dental implants offers potential benefits for patient treatment timelines.
- The denture conversion protocol provides a method for fabricating implant-supported prostheses from existing dentures.
- Evaluating the survival and complication rates of these prostheses is crucial for clinical adoption.
Purpose of the Study:
- To assess the survival outcomes of immediately loaded acrylic resin complete arch fixed implant-supported prostheses (CAFIP) created using the denture conversion protocol.
- To determine the early survival rates of dental implants associated with these prostheses.
Main Methods:
- A retrospective chart review of 117 patients who received immediately loaded acrylic resin CAFIP via the denture conversion protocol over 9 years.
- Data collected included implant failures, prosthetic fractures, technical complications, and opposing dentition.
- Statistical analysis was performed with a significance level of p < 0.05.
Main Results:
- 153 prostheses and 768 implants were evaluated, with a 98% implant survival rate and a 94.1% complication-free survival rate for the prostheses within 4 months.
- Early critical prosthetic complications (fractures) occurred in 9 prostheses (5.9%), with statistically significant differences between maxillary and mandibular arches (p=0.037).
- Only 3 implant failures were associated with prosthetic failures during the healing period.
Conclusions:
- The denture conversion protocol demonstrates a high early survival rate for both dental implants (98%) and immediately loaded prostheses (94%).
- This protocol is a simple, evidence-based, and predictable method for immediate implant loading.
- Minimal implant failures and non-critical complications were observed with this technique.

01:11Clinical Trials: Overview
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...
01:16Bioequivalence: Overview
Pharmaceutical equivalents, by definition, are drug products with the same active ingredient in the same quantities, encapsulated in identical dosage forms, and intended for the same administration routes. These pharmaceutical equivalents are deemed bioequivalent if the bioavailability of the active entity in the drug preparations is similar. Moreover, pharmaceutical equivalents demonstrating bioequivalence are also regarded as therapeutically equivalent. This means that when used as directed,...
01:15Bioavailability Study Design: Healthy Subjects Versus Patients
Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...
01:17Equivalence: In Vitro and In Vivo Bioequivalence
Bioequivalence studies are crucial in evaluating whether new drugs can match an approved one regarding pharmacological effects and clinical performance. These studies test if drugs, despite different dosage forms, share identical plasma concentration-time profiles. Three types of equivalence are central to these studies: chemical, pharmaceutical, and therapeutic. Chemical equivalence indicates that two or more drug products contain identical active ingredients in equal amounts. Pharmaceutical...
01:20Drug Product Performance: In Vitro–In Vivo Correlation
In pharmaceutical development, it's crucial to establish a predictive in vitro–in vivo correlation (IVIVC) for two or more formulations to gain a comprehensive understanding of release properties. IVIVC reduces the need for costly in vivo studies and facilitates the establishment of meaningful dissolution specifications with significant cost savings and decreased regulatory burden. Furthermore, a meaningful IVIVC should predict Cmax and AUC within 20%, aligning with FDA guidance while adhering...
01:22Pharmaceutical Alternatives: Stability-Related Therapeutic Nonequivalence
Generic intravenous (IV) drugs are considered bioequivalent to their branded counterparts due to their 100% bioavailability upon administration. However, variations in stability among different drug products can significantly influence their therapeutic performance, even if they are pharmaceutically equivalent.Cefuroxime, a prophylactic antimicrobial, is often used as a single-dose IV injection for patients undergoing coronary artery bypass grafting surgery. A 3 g dose typically provides...
