The implants were inserted and the buccal gaps were grafted by AB. A subgroup of 34 sites was grafted additionally with CTG using tunnel technique. Primary outcome was the vertical bone regeneration in height and thickness. Secondary outcome parameters were interproximal marginal bone level, recession, soft tissue esthetics (PES), width of keratinized mucosa (KMW) and probing depths (PPD).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Mean follow-up period was 60.8\u00a0months. In 55 sites a complete vertical bone regeneration was documented. The mean buccal bone level increased by 10.6\u00a0mm significantly. The thickness of the buccal bone wall ranged between 1.7 and 1.9\u00a0mm, and was significantly thicker in sites without CTG. Interproximal marginal bone level was at implant shoulder level. The mean recession improved significantly by 1.2\u00a0mm.
