Two of 3x14 (2) mm 1-piece implants are placed at #8 and 9 (Fig.3). The patient returns with fractured 3-unit provisional 4 months postop. There is crestal bone loss, most likely palatal (Fig.11 ^). There is no sign of peri-implantitis. Use of smaller 1-piece implants may reduce bone loss (such as 2.5 or 2.0 mm in stead of 3.0 mm). There is increased bone loss 1 year 2 months post cementation (Fig.17, particularly at #8: *), although the gingiva remains healthy (Fig.18). Smaller 1-piece implants (2 or 2.5 mm) or lower torque (increase in osteotomy) may be associated with less bone resorption. It is necessary to check occlusion.
