Total number of large‐ and small‐sized blood vessels in biopsies taken after maxillary sinus floor elevation (MSFE) with retromolar or tuberosity bone graft. (A) Blood vessel number was calculated in biopsies stained with Goldner's trichome taken after MSFE with retromolar or tuberosity bone graft. Images illustrate less blood vessels in retromolar than in tuberosity bone biopsies (RII region). Black dotted circumferential line: blood vessel. (B) Total number of blood vessels (N.Bloodves), and (C) Percentage of large‐ and small‐sized blood vessels was assessed for NB, TZ, Rl, Rll, and Rlll. Values are mean ± SEM (n = 3–9). *Significantly different between retromolar and tuberosity bone graft, p < 0.05. NB, native bone; N.Bloodves, number of blood vessels; RI, region I; RII, region II; RIII, region III; TZ, transition zone. Magnification: 100×. Scale bar: 100 μm.
