IMMEDIATE PLACEMENT OF IMPLANT IN FRESH EXTRACTION SOCKET WITH
EARLY LOADING

Early loading, fresh extraction socket, and gingival architecture immediate
placement
Abstract
Implant placement in maxillary anterior region has most aesthetic challenges in implant
dentistry because tooth loss lead to bone resorption and collapse of gingival architecture, which
lead to aesthetic compromise and inadequate bone for implant placement. Immediate implant
placement into fresh extraction socket reduces the treatment time, cost, preserved the gingival
aesthetic and increases the comfort of the patient. This article describes the procedure for
immediate implant placement in fresh extraction socket and early loading of implant with
zirconia crown. Clinical and radiographic examination revealed width and length of the tooth for
selecting implant size and design. Cement retained zirconia crown was used for early loading.
Implant was successfully loaded and was functional during 36 months follow up period.
Immediate placement and early loading of dental implant provides advantages like fewer
surgical procedures, shorter treatment time, and improved aesthetic and psychological
confidence. Loss of tooth in the aesthetic zone is a traumatic experience with or without
compromise in phonetics. Hence, in the aesthetic zone implant supported single tooth
replacement is one of the most challenging situations confronting the clinician. According to the
traditional protocols 3-4 months of healing period is required for the consolidation of extraction
socket. Taking into account the prosthetic treatment, patients frequently are required to wait up
to 1 year for replacement of a lost tooth.

Immediate implant and early loading may be a good treatment option in the loss of anterior
teeth.[
] Its success rate in maxilla is 66%-95.5% and in mandible 90%-100%.[
] Immediate
implant placement is most commonly indicated when tooth extraction is due to trauma,
endodontic lesion, root fracture, root resorption, root perforation, unfavourable crown to root
ratio (not due to periodontal loss) and bony walls of alveolus are still intact.[
] Contraindications
includes presence of active infection, insufficient bone (<3 mm) beyond the tooth socket apex for
initial implant stability and wide and/or long gingival recession. Prior to extraction of tooth it
was aesthetically evaluated to comprehensively assess the potential implant placement site. A
proper plan was made which included soft tissue treatment protocol and set of well defined
aesthetic goals. Under three parameters the prospective implant site was evaluated to predict the
peri-implant aesthetic outcome these are tooth position and shape, form and bio-type of the
periodontium and position of osseous crest.
The surgeon may wish to consider loading the newly placed implant immediately or early
when anyone of the following condition exist at implant site: when primary stability is obtained,
bone is type I or II, site can accommodate implant with a length of at least 13 mm or minimum 3
mm of apical bone present, diameter of the head of the implant closely matches the mesio-distal
with of coronal aspect of the socket, no need for bone augmentation procedure, once placed the
implant can be completely protected from function and occlusal forces.[
] The initial stability
of the implant is essential for early/immediate loading. The minimum insertion screw has to be
equal or superior to 32 N/cm and the micro movement of the implant should not exceed 150 um.
Bruxism and the lack of primary stability of the implants are contraindications for the immediate
loading.[
] In this case report, primary stability was achieved and no need for bone
augmentation because the implant diameter closely matches the socket dimension.
Immediate/early loading of implant requires an understanding of the biology of the recipient
tissue, the surgical trauma, the wound healing process and occlusion. Wound healing studies
have demonstrated that early osteoid formation begins after 7 day, mineralization commences at
21 days thus implant loading after 2-3 weeks may therefore turn into a feasible protocol.[
] In
this case report implant is loaded after 2 week and during 3 year of follow-up there is minimum
bone loss occur.Dental implants that are immediately placed and loaded into carefully selected
extraction socket have high survival rates comparable to implant placed in healed site.[
] In this
case report we are pleased with the gingival aesthetic. Studies have confirmed that immediate
loading will produce excellent gingival aesthetics. Although in this study only two patient visits
were needed to achieve this result, our real goal is to show the potential to reduce time and
improve patient satisfaction.
This case report demonstrates that it is possible to achieve greater efficiency in our efforts
to give patient sound, timely and economical treatment. This procedure is still technique
sensitive, but it is clear that with continued innovation in the prosthetic capabilities of implant
system we should be able to enhance the service and treatment offered to our patients in regard
to our treatment time, patient comfort, cost and aesthetics.

осложнения, возникающие после удаления зубов) представляют собой одну из важнейших
проблем стоматологии, что объясняется следующими причинами. Во-первых, высокая
