Immediate Rehabilitation of the Extremely Atrophic Mandible with Fixed Full‐Prosthesis Supported by Four Implants

Abstract

This technique could be considered a viable treatment option for the rehabilitation of the atrophic mandible.

Tilted versus axially placed dental implants: A meta-analysis

“…Seventeen studies 3,7,14,17,19,20,23,29,32,33,36,37,39,45,47,49,51 exclusively evaluated implants inserted in maxillae, and exclusively evaluated implants inserted in mandibles in eleven studies. 1, 18,21,28,30,31,42,44,46,48,50 Implants were not immediately loaded in eight studies 7,13,37,38,43,47,48,51 In one study 36 some implants were immediately or delayed loaded, and another study 41 did not provide information about the healing/loading time. Twenty-three studies 8,13,[15][16][17]20,21,23,25,26,31,33,37,…”

“…All studies but two 16,52 provided information of the patients' age, and none of them included non-adults patients. Some patients in thirty-three studies 1, 3,7,8,14,15,17,18,[20][21][22][23][24][25][27][28][29][30][32][33][34]36,[40][41][42][44][45][46][47][48][49]51,52 were smokers. Five studies 16,42,44,46,49 reported the presence of bruxers among the patients, and six studies 1, 28,42,46,48,49 the presence of diabetic patients.…”

“…There were no implant failures in twelve studies. 17 Nobel Biocare AB (Gö teborg, Sweden) were the most commonly used, in twenty-seven studies, 1, 3,7,14,[16][17][18]21,22,26,27,[29][30][31][32][33]35,37,39,40,42,43,[45][46][47]50,52 most of them with an oxidised surface. Four studies 25,36,38,51 did not inform what kind of implants was used.…”

“…Four studies 25,36,38,51 did not inform what kind of implants was used. Thirty studies 1, 3,8,[14][15][16][17][18][19][20][21][22]24,26,[28][29][30][31][32][33]35,[37][38][39][40]44,45,[49][50][51] provided information about the use of prophylactic antibiotics. Twenty studies 14,[17][18][19]21,22,[24][25][26][28][29][30][31][32][33][34]38,44,45,…”

“…In twenty-three studies 1, 3,8,16,18,21,22,[24][25][26][27][28]30,31,35,39,42,45,46,[48][49][50]52 the patients were exclusively rehabilitated with fixed full-arch prostheses receiving 2 distal tilted implants and 2 mesial axially placed implants. Patients were submitted to grafting procedures at the implant site in only two studies.…”
