No. | Study (year) | Study design | Type of reconstruction | Number of subjects | Outcome |
---|---|---|---|---|---|
1. | Batisse et al. (2014) | RCT - crossover design - double-blinded - without follow-up |
A1. Tooth-borne crowns - n = 10: monolithic LS2 - n = 10: metal-ceramic (gold-alloy) |
8 patients [10 crowns]: randomized treatment sequence |
Esthetics: - patients & operators preference. |
2. | Batson et al. (2014) | RCT - 3-armed design - non-blinded - without follow-up |
A1. Tooth-borne crowns - n = 10: monolithic LS2 - n = 10: monolithic ZrO2 - n = 12: metal-ceramic (gold-alloy) |
22 patients [32 crowns]: 3 randomized groups |
Marginal discrepancy / precision: - micro-computed tomography; Quality of soft tissue response: - gingival crevicular fluid rates. |
3. | Joda & Bragger (2016) | RCT - 2-armed design - non-blinded - without follow-up |
B1. Implant-supported crowns - n = 10: monolithic LS2 - n = 10: ZrO2 coping veneered |
20 patients [20 implant-crowns]: 2 randomized groups |
Feasibility testing; Time-efficiency: - clinical & technical workflows. |
