The aim of this study was to compare the implant survival rate between short dental implants (6 mm) and regular length implants (11\u201313 mm) when placed in combination with bone grafting and loaded with a single non splinted crown, seven years after placing the implant. It was conducted as a controlled clinical study of 30 patients with partial edentulism in the posterior maxilla. The protocol included radiological and clinical evaluation of the C\/I ratio (length of the superstructure divided by the length of the implant crestal part), marginal bone level (MBL), ultrasonography measurement of soft tissue surrounding implant (STT), patient-reported outcomes, and biological and technical complications. A total number of 28 implants (93%) remained integrated during follow-up period. MBL of 0.50 and 0.52 mm was observed for short implants and regular implants, respectively. MBL was checked for correlation with STT, and a negative correlation was found between MBL: STT. Our study has demonstrated a significantly lower implant survival rate for short implants compared to regular implants (87% compared to 100%). Despite the loss of several implants, good clinical results were achieved in the remaining implants in both groups. It is, therefore, worth considering short implants as an alternative to regular implants with a sinus lift surgery.<\/jats:p>","DOI":"10.3390\/jcm10050940","type":"journal-article","created":{"date-parts":[[2021,3,1]],"date-time":"2021-03-01T03:35:40Z","timestamp":1614569740000},"page":"940","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Short (6 mm) and Regular Dental Implants in the Posterior Maxilla\u20137-Years Follow-up Study"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2353-3198","authenticated-orcid":false,"given":"Jakub","family":"Hadzik","sequence":"first","affiliation":[{"name":"Department of Dental Surgery, Wroc\u0142aw Medical University, 50-425 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pawe\u0142","family":"Kubasiewicz-Ross","sequence":"additional","affiliation":[{"name":"Department of Dental Surgery, Wroc\u0142aw Medical University, 50-425 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5797-7336","authenticated-orcid":false,"given":"Izabela","family":"Nawrot-Hadzik","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Biology and Botany, Wroc\u0142aw Medical University, 50-367 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomasz","family":"Gedrange","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Dresden University of Technology, 01069 Dresden, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Artur","family":"Pitu\u0142aj","sequence":"additional","affiliation":[{"name":"Department of Dental Surgery, Wroc\u0142aw Medical University, 50-425 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8943-0549","authenticated-orcid":false,"given":"Marzena","family":"Dominiak","sequence":"additional","affiliation":[{"name":"Department of Dental Surgery, Wroc\u0142aw Medical University, 50-425 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"73","DOI":"10.1111\/prd.12167","article-title":"Clinical relevance of dimensional bone and soft tissue alterations post-extraction in esthetic sites","volume":"73","author":"Chappuis","year":"2017","journal-title":"Periodontology 2000"},{"key":"ref_2","first-page":"313","article-title":"Bone healing and soft tissue contour changes following single-tooth extraction: A clinical and radiographic 12-month prospective study","volume":"23","author":"Schropp","year":"2003","journal-title":"Int.
