In Vitro Accuracy of Digital Versus Conventional Workflows for Complete-Arch Implant- Supported Frameworks-A Scoping
The International Journal of Prosthodontics
|August 7, 2024
Summary
Digital workflows offer superior accuracy for complete arch implant supported frameworks compared to conventional methods. However, more research is needed to assess the cumulative errors and clinical relevance of these dental implant procedures.
Area of Science:
- Dental materials science and biomaterials
- Biotechnology and biomedical engineering
- Prosthodontics
Background:
- Complete arch implant supported frameworks are crucial for restoring edentulous arches.
- Evaluating the accuracy of fabrication workflows is essential for predictable clinical outcomes.
- Conventional and digital methods present different approaches to framework fabrication.
Purpose of the Study:
- To systematically review and synthesize evidence on the accuracy of conventional versus digital workflows for complete arch implant supported frameworks.
- To assess the potential for statistical analysis of error accumulation in these workflows.
- To identify gaps in the current research regarding accuracy assessment and clinical relevance.
Main Methods:
- A scoping review following the Arksey and O'Malley framework.
- Systematic literature search adhering to PRISMA guidelines.
- Inclusion of 58 in-vitro studies (2000-2024) comparing conventional and digital methods for edentulous arches with ≥4 implants.
Main Results:
- Evidence exists for accuracy assessment, but heterogeneity prevents statistical analysis of cumulative errors.
- Digital techniques demonstrate superior accuracy in complete arch implant supported framework fabrication compared to conventional casting.
- No consensus was found regarding the impression and cast fabrication stages between the two methods.
Conclusions:
- Digital workflows show higher accuracy for complete arch implant supported frameworks than conventional methods.
- Further in-vitro studies are required to evaluate the accuracy of entire workflows.
- Research needs to focus on classifying outcomes based on clinical relevance for these dental prostheses.

01:23Design of Prismatic Beams for Bending
The design of prismatic beams, structural elements with a uniform cross-section, focuses on ensuring safety and structural integrity under load. The design process begins by determining the allowable stress, either from material properties tables, or by dividing the material's ultimate strength by a safety factor. This safety factor is essential for accommodating uncertainties, and varies depending on the material—timber, steel, or concrete—with each having unique strength and stress...
01:12Adjusting a Traverse
In the site survey of a four-sided traverse, internal angles are essential to ensure geometric accuracy. The survey revealed that the sum of the measured internal angles was 359 degrees and 48 minutes, which is 12 minutes less than the expected 360 degrees. This discrepancy signals an error likely arising from measurement inaccuracies during the fieldwork.To rectify this error, the adjustment process involved distributing the 12-minute shortfall equally across the four internal angles. By...
01:26Field Procedure for Staking Out Curves
Staking out curves is an essential process in construction to ensure the accurate alignment of structures along a curved path. This task involves positioning stakes at calculated locations corresponding to the curve's design, effectively translating plans into physical markers in the field. The process begins by determining the geometric parameters of the curve, including the radius, central angle, and tangent distances. These parameters are critical for identifying key points such as the Point...
