Enhanced Patient Satisfaction with Digital Impressions Using 3Shape TRIOS 3 Move Scanner for Single-Implant Crowns
Abstract
:1. Introduction
2. Methods
2.1. Study Design
2.2. Study Subjects
2.3. Inclusion Criteria
- Patients aged 18 years or older.
- Single-tooth loss in the posterior maxilla or mandible, with implants placed for at least four months and assessed for osseointegration via CBCT imaging.
- The implant site must have healing abutments placed for a minimum of two weeks prior to the study.
- Presence of at least one adjacent tooth or prosthetic restoration near the implant site, with an edentulous gap greater than 6 mm and prosthetic space greater than 5 mm.
- The opposing teeth must be either natural teeth, restorations of natural teeth, or restorations on implants.
- All patients selected for the study had implants from the same manufacturer (Naturactis, Euroteknika, Sallanches, France).
2.4. Exclusion Criteria
- Patients with mental disorders, or those who are mute, deaf, or unable to communicate effectively with the interviewer.
- Individuals with allergies to any components of the impression material.
- Patients who are unable to return for follow-up visits within three months after prosthetic placement.
- Patients who declined to participate in the study at any point.
2.5. Sample Size
- α = 0.05
- β = 0.2
- C = (Z1−α/2 + Z1−β)2 = 7.85
- ES = Δ/∂
- ∂: standard deviation
2.6. Procedures
2.7. Evaluation of Impression Time
2.7.1. Conventional Impression Time
- Removing the healing abutment and attachment of the impression coping.
- Taking an impression of the arch containing the implant.
- Taking an impression of the opposing arch.
- Recording the bite in maximum intercuspation.
2.7.2. Digital Impression Time
- Removing the healing abutment and attachment of the digital impression coping.
- Scanning of the arch containing the implant.
- Scanning of the opposing arch.
- Scanning of the bite in maximum intercuspation.
2.8. Evaluation of Patient Satisfaction
- Satisfaction with the time required for the impression process.
- Anxiety level during the impression process.
- Overall convenience of the impression technique.
- Level of discomfort or pain during the impression.
- Taste experience during and after the impression.
- The degree of nausea caused by the impression.
2.9. Bias Control
- Participant selection: Study participants were carefully selected based on predefined inclusion and exclusion criteria to ensure homogeneity and relevance to the research objectives.
- Standardized procedures: All clinical procedures, including impression taking, trial fittings, and final prosthesis placement, were performed exclusively by the principal dental researcher. This individual possesses a minimum of 5 years of experience in implant prosthetics and is proficient in the use of intraoral scanners (IOSs), ensuring consistency and precision throughout the study.
- Randomization: A randomization process was employed to determine the sequence of impression methods (digital vs. conventional) and the order in which the crowns were tried. Both crowns were fabricated by the same dental technician, following a randomized sequence to eliminate bias. Measurements were conducted using Geomagic Control X software, with all analyses performed by a single technician to maintain consistency and accuracy.
- Questionnaire administration: The patient satisfaction questionnaire was pre-tested and refined to ensure clarity and reliability. Data collection was carried out by a single individual to minimize variability, and all research instruments were calibrated to guarantee precision and reproducibility.
