TABLE 1.

Overview of the three predictors (i.e., BBT, abutment/crown material, and implant diameter) in relation to the two main outcome parameters “correct diagnosis of the presence/absence of a buccal bone dehiscence” and “difference between direct and CBCT measurements of the buccal bone level” (based on the observations with an actual dehisce)

Predictor	Group	Main outcome parameter
		Diagnosis of the presence/absence of a buccal bone dehiscence					Difference between direct and CBCT measurements of the buccal bone level
		n a	Presence of a buccal bone dehiscence (n = 72)		Absence of a buccal bone dehiscence (n = 72)		n b	Mean ± SD (mm)	Median (1Q; 3Q) (mm)
			Correctly diagnosed	Wrongly diagnosed	Correctly diagnosed	Wrongly diagnosed
BBT	Group 1	48	23	1	3	21	24	1.61 ± 1.88	0.90 (0.51; 2.24)
	Group 2	48	24	0	20	4	24	0.50 ± 0.63	0.34 (0.17; 0.50)
	Group 3	48	24	0	17	7	24	0.43 ± 0.36	0.34 (0.16; 0.59)
Abutment/crown material	Ti/MCC	72	36	0	19	17	36	0.93 ± 1.19	0.46 (0.24; 1.15)
	Zirconia	72	35	1	21	15	36	0.77 ± 1.36	0.44 (0.22; 0.66)
Implant diameter	Narrow	72	36	0	19	17	36	0.83 ± 1.39	0.35 (0.24; 0.95)
	Standard	72	35	1	21	15	36	0.86 ± 1.16	0.48 (0.22; 1.00)

1Q/3Q; First/third quartile; BBT, buccal bone thickness; CBCT, cone‐beam computed tomography; Ti/MCC, titanium/metal‐ceramic crown.

^aNumbers represent observations per group resulting in total in 144 observations per predictor (i.e., all blocks are considered for this outcome parameter).

^bNumbers represent observations per group resulting in total in 72 observations per predictor (i.e., only those blocks with a dehiscence are considered for this outcome parameter).
