1. Chen, Zesheng. Accuracy of Composite Attachment Position with Four Different Indirect Bonding Techniques.

Degree: 2019, University of Illinois – Chicago

URL: http://hdl.handle.net/10027/23846 

Introduction: Our objective was to evaluate the attachment transfer accuracy of four indirect bonding technique variations based on tray sectioning. Materials and Methods: Twenty 3D printed dental models without attachments were bonded with composite resin attachments using 0.5mm thermoform plastic template trays fabricated from physical reference models. Four IDB technique variations were studied, n=5 for each technique: 1) whole arch (Whole), 2) whole arch, buccal segment only (Halves), 3) sextants (Thirds), and 4) sextants, buccal segment only (Sixths). Dimensional deviation of attachment position was evaluated in the buccal-lingual (B/L), mesial-distal (M/D), incisal-gingival (I/G) dimensions, and in tip through model digitization and 3D software superimpositions with the reference digital model. Clinical significance cutoffs were set at 0.25mm for linear measurements and 1° for angular measurements. ANOVA and multiple comparisons were performed. Statistical significance was set at 0.05. Results: Across all techniques, a total of 142 attachments were evaluated. B/L- Left side attachments had more mean discrepancy than right side attachments, and there was a lingual bias of all attachments. M/D- The Thirds group had less deviation than all other techniques (p < 0.05). Across all attachments, there was virtually zero bias towards the mesial or distal. I/G- The Wholes and Sixths groups had the least and greatest deviation, respectively, and the difference was significant (p < 0.05). There was an incisal bias across all attachments. Tip- There was approximately a 1° distal root tip bias across all attachments. Overall, no mean linear deviations reached the clinical significance threshold, but mean angular deviations did. Conclusions: In general, all IDB techniques studied achieved clinically acceptable and similar attachment positions in the B/L, M/D, I/G, dimensions, and marginally acceptable tip angulation.

2. Tran, Johnny. Effect of Clear Aligner Therapy on Masticatory Muscle Tenderness and Orthodontic Pain.

Degree: 2018, University of Western Ontario

URL: https://ir.lib.uwo.ca/etd/6014 

Introduction: Patients undergoing orthodontic clear aligner therapy (CAT) may experience discomfort in their teeth and jaws, and often present with visible wear on their aligners. This multi-site prospective clinical study aimed to analyze tooth pain and masticatory muscle tenderness in patients subjected to CAT with Invisalign©. Methods: Twenty-seven healthy adults undergoing treatment with Invisalign© were recruited from three university-based orthodontic clinics. Tooth pain and muscle tenderness were reported on visual analog scales in pain diaries prior to, and after starting CAT. Pressure pain thresholds (PPT) measured using pressure algometers were used to assess somatosensory changes in trigeminal and extra-trigeminal locations. Results: The aligners resulted in tooth pain, which was greater with the initial passive aligner than the subsequent active aligners (all p0.05). Conclusion: In the short-term, CAT results in mild tooth pain and jaw muscle tenderness of likely limited clinical significance, and does not result in significant somatosensory changes.

3. Teske, Lauren Evan Montoure. Mechanical Properties and Patient Perceptions of Commonly Used Clear Aligner Systems As-Received and After Clinical Use.

Degree: 2015, Marquette University

URL: https://epublications.marquette.edu/theses_open/326 

Background/Objectives: This study aimed to investigate the viscoelastic properties of two clear aligner systems, Invisalign (Align Technology, Inc, Santa Clara, CA, USA) and Simpli5 (Allesee Orthodontic Appliances, Sturtevant, WI, USA), and determine if there was a difference after use. A survey assessed patients’ perceptions of the aligner material and post-treatment satisfaction. Materials/Methods: Mandibular aligners were collected from two patients after 2-3 weeks of use (n=6). Duplicate, unused aligners were obtained for each patient (n=6). Dynamic mechanical analysis (DMA) characterized the viscoelastic properties of the materials. Three tests were done on separate specimens: frequency scan (0.1-10 Hz under 25 μm displacement at 37 °C), creep-recovery (1 N, 2 N and 3 N at 37 °C) and temperature ramp (28o-120 °C at 5 °C/min under 1 Hz and 25 μm displacement). The survey was given to sequential patients (n=7) after completing aligner therapy. Repeated measures of multivariate analysis of variance were performed. Results: No statistically significant difference in storage modulus, loss modulus, tan δ, creep compliance, or strain recovery was found comparing the materials in as-received and after-use states, and no significant difference was found between Invisalign and Simpli5 (p>0.05). The tan δ (loss modulus/storage modulus) values for as-received Invisalign and Simpli5 at 1 Hz were 0.056±0.01 and 0.093±0.03. The creep compliance (μm2/N) for as-received Invisalign and Simpli5 were 300±50 and 155±36. Strain recoveries were >94%. Patients’ survey responses were predominately positive, as all were pleased with the esthetics, comfort, and performance of the aligners. Conclusions: While there was no significant difference between the materials before or after use, both Invisalign and Simpli5 demonstrated favorable qualities, including low tan δ values and positive patient perception of the material.
