Partial and Complete-Arch Implant-Supported Fixed Dental Prostheses in Fully Digital Workflow Using Neuromuscular and
The International Journal of Prosthodontics
|February 13, 2026
Summary
This study compared digital dental prostheses, finding partial-arch fixed dental prostheses (P-FDPs) had greater bone loss, while complete-arch fixed dental prostheses (CA-FDPs) had more chipping complications.
Area of Science:
- Digital dentistry
- Implantology
- Prosthodontics
Background:
- A fully digital workflow using neuromuscular and jaw-tracking systems was developed for fabricating implant-supported fixed dental prostheses.
- This workflow aims to improve precision and efficiency in full-mouth rehabilitation.
Purpose of the Study:
- To evaluate the clinical outcomes of partial implant-supported fixed dental prostheses (P-FDPs) versus complete-arch implant-supported fixed dental prostheses (CA-FDPs) fabricated using a novel digital workflow.
- To compare prosthesis delivery time, survival and success rates, prosthetic complications, and marginal bone loss (MBL) between P-FDPs and CA-FDPs.
Main Methods:
- A retrospective review of clinical records for participants undergoing full-mouth rehabilitation with the digital protocol.
- Evaluation of implant and prosthesis survival/success rates, prosthetic complications, and marginal bone loss (MBL) over a mean follow-up of 6.5 years.
- Statistical analysis using the Mann-Whitney U test to compare outcomes between P-FDP and CA-FDP groups.
Main Results:
- Implant and prosthesis survival rates were 100% in both P-FDP and CA-FDP groups.
- Implant success rates were 95.2% for P-FDPs and 100% for CA-FDPs.
- P-FDPs showed significantly higher annual marginal bone loss (0.09 mm) compared to CA-FDPs (0.04 mm; P < .001), while CA-FDPs experienced prosthetic complications (25% chipping).
Conclusions:
- The digital workflow effectively rehabilitates patients with implant-supported fixed dental prostheses.
- Partial implant-supported fixed dental prostheses demonstrated significantly greater marginal bone loss.
- Complete-arch implant-supported fixed dental prostheses showed a higher incidence of prosthetic complications, specifically chipping.

The Arch of Aorta
2.0K
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

Self-Help Support Groups
369
Self-help support groups are voluntary, community-based organizations that provide a platform for individuals with shared concerns to exchange support, insights, and practical strategies for coping with life challenges. Typically led by group members or paraprofessionals, these groups form a cornerstone of mental health care, especially in reaching populations that are underserved by traditional healthcare systems.

Fixed Action Patterns
17.7K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Parenteral Drug Delivery Systems: Injectables, Implants, and Infusion Devices

Parenteral drug delivery systems play a crucial role in modern therapeutics by enabling the direct administration of drugs into the systemic circulation, bypassing the gastrointestinal tract. These systems are particularly valuable for poorly absorbed oral medications that are unstable in the digestive environment or require rapid onset or sustained therapeutic levels. Delivery is achieved through intravenous, intramuscular, or subcutaneous routes, each selected based on the drug's properties...

Partial Fractions
232
A partial fraction is a component of a rational expression represented as the sum of simpler fractions. When a rational function is expressed as a ratio of two polynomials, it can often be decomposed into a sum of fractions whose denominators are simpler polynomials, typically linear or irreducible quadratic factors. This process is called partial fraction decomposition, and it is used to simplify complex expressions for integration, solving equations, or analysis.Partial fraction decomposition...

The Neuromuscular Junction
19.7K
The nervous system consists of complex motor neuron circuits, including upper motor neurons originating from the cerebral cortex and lower motor neurons starting in the spinal cord, coordinating both voluntary and involuntary movements. Among these, somatic motor neurons activate skeletal muscles and are classified into alpha, beta, and gamma types. Alpha neurons are vital for voluntary movement coordination, while gamma neurons adjust muscle spindle sensitivity, and the function of beta...
