•Tooth space width at least 7 mm, allowing for an implant insertion before the study starts or as the case may be, state after two\-stage augmentation or internal sinus lift or one\-stage minor extent lateral Augmentation;
•at least 2 mm gingival height;
•legally competent patient with supply needs

•Need for major extent lateral augmentation in a one\-stage procedure (meaning that two\-stage bone block surgery can be included as well as internal sinus lift or minor extent lateral augmentation)
•Need for application of a soft tissue transplant
•Implant insertion using a surgical template was impossible before the study starts
•Tooth space width is smaller than 7 mm (The interdental papilla would be severed during punch biopsy in this case)
•Less than 2 mm gingival height in the lowest most area
•Lack of informed consent
•Chronic diseases
•Pregnancy
•Alcohol\- or drug abusus
•Anamnestic peculiarities, ruling out implant treatment before the study starts
