Case of immediate implant into the active infective site









A Case of young female was suffered from fistula over labial side of upper R't central incisor .
We extracted the ill tooth and debride all granulation tissue ,placed implant with little primary stability . Even though there was large bony defect ( 15mmx8mm) ,we still believe it should be work duing to its 3-wall bony defect. We grafted with Bio-Oss and Tuodem membrane over the defect . Keep close follow-up




wo, we finally finished this case with acceptable result on 2007/11/14 .

Short dental implant study

Short Dental Implants in Posterior Partial Edentulism: A Multicenter Retrospective 6-Year Case Series Study
Carl E. Misch et. al.
Methods:
A retrospective evaluation of 273 consecutive posterior partially edentulous patients treated with 745 implants, 7 or 9 mm long, supporting 338 restorations over a 1- to 5-year period was reviewed from four private offices.
Implant survival data were collected relative to stage I to stage II healing, stage II to prosthesis delivery, and prosthesis delivery to as long as 6 years follow-up.
A biomechanical approach to decrease stress to the posterior implants included splinting implants together with no cantilever load, restoring the patient with a mutually protected or canine guidance occlusion, and selecting an implant designed to increase bone-implant contact surface area.
Results:
Of the 745 implants inserted, there were six surgical failures from stage I to stage II healing. All five failures were with a one-stage surgical approach (240 implants). There were two failures from stage II healing to prosthesis delivery. No implants failed after the 338 final implant prostheses were delivered. A 98.9% survival rate was obtained from stage I surgery to prosthetic follow-up.
Conclusions:
Short-length implants may predictably be used to support fixed restorations in the posterior partial edentulism. Methods to decrease biomechanical stress to the bone-implant interface appear appropriate for this treatment.

My Nordic review tour--stockholm city tour



Stockholm – The Capital of Scandinavia
There are many reasons why Stockholm is the natural Capital of Scandinavia. One is that Stockholm is positioned at the heart of the region, and enjoys the benefits of a world-class transport infrastructure. Another is that Stockholm is the largest city in the largest country in Scandinavia.
It is also where you find the most multinational companies, the largest stock market and, not least, the most visitors. People come to Stockholm for the food, the design and the music. Stockholm also offers a unique range of galleries and museums, and every year the eyes of the world are on Stockholm when the Nobel Prizes are awarded.

regeneration of intrabony defect : EDTA ?

Effect of EDTA Root Conditioning on the Healing of Intrabony Defects Treated With an Enamel Matrix Protein Derivative JP 2006, Vol. 77, No. 7, Pages 1167-1172

The purpose of this study was to determine the effect of root conditioning on the healing of intrabony defects treated with EMD.
Methods: Twenty-four patients, each of whom exhibited one deep intrabony defect, were randomly treated with either open flap debridement (OFD) followed by root surface conditioning with EDTA and application of EMD (OFD + EDTA + EMD) or with OFD and application of EMD only (OFD + EMD). The following parameters were recorded at baseline and at 1 year: plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), and clinical attachment level (CAL).
Results: No differences in any of the investigated parameters were observed at baseline between the two groups. Healing was uneventful in all patients. At 1 year after therapy, the OFD + EDTA + EMD group showed a reduction in mean PD from 9.3 ± 1.3 mm to 4.0 ± 0.9 mm (P <0.001), color="#ffff00">There were no significant differences in any of the investigated parameters between the two groups.
Conclusion: In intrabony defects, regenerative surgery including OFD + EDTA + EMD failed to show statistically significant differences in terms of PD reduction and CAL gain compared to treatment with OFD + EMD.

Vertical dimension elevation with implant therapy in post-radiotheraphy NPC patient


A case who was gum impinged bite had been received radiotherapy because of NPC .
We elevated his vertical dimension and reconstructed occlusion with implant.

The origin of Astra implant design

Biomechanical aspects --
Original from " Galileo G (1638) --- Bone size is directly correlated with body weight and activity
Von Meyer H. & C.Culmann(1867) --- There are direct relationship between the structure of cancellous of the bone and direction of loading . The bone structure is similar to the architecture design .
Wolff's law (1892) --- The law of bone transformation
The first one who combined the above two findings .
A bone .. develpos the structure best suited to resist the force acting upon it.
Wolff's law applies to pro tennis players
Humeral cortical thickness on playing side is greater by 34.9% on men and 28.4% on women compared with control side . ( Jones HH et al 1977 Bone Joint Surg Am 204-208)
Wolff's law applies to astronauts
A device delivering a mechanical impluse intended to mimic the heel strike transient
(Goodship et al 1998 Acta Astronaut 65-75)

local drug therapy in periodontal disease

Several local drug delivery systems employed as monotherapies improved periodontal health and provided results that were not statistically significantly different than attained with scaling and root planing (SRP) alone. In contrast,many local drug delivery devices when used as adjuncts to SRP provided a statistically significant enhancement of parameters commonly used to monitor periodontal status. However,meanimprovements with respect to probing depth reduction or gainof clinical attachment were often limited to tenths of millimeters.Several devices also achieved specific criteria that canbe used to identify clinically significant findings (e.g., numberof sites with probing depth reduction ‡2 mm). However, there are conflicting datawith respect to the ability of local drug deliveryto enhance results of SRP at deep probing sites, and there is limited information relative to its capability to inhibit disease progression or enhance osseous repair in infrabony defects. Conclusion: The decision to use local drug delivery during active treatment or maintenance should be based upon clinical findings, responses to therapy recorded in the literature, desired clinical outcomes, and the patient’s dental and medical history.

股市人生

胡立陽先生故事 : 我有一次到英國探望一個朋友,這個朋友養了大約 200 頭羊,他的羊每次參加比賽都得冠軍。他除了可以精準的叫出每一隻羊的名字和特徵外,還能告訴我哪隻羊心情好、哪隻羊好像不太舒服。對我來說每一隻羊都是一樣的,我並不能看出其中的分別。我看股票就好像他看羊一樣,鎖定一籃子的股票後,就開始像養羊一樣,觀察這些股票的一舉一動,其他股票我都不看,我在華爾街時就是這樣連看 3 - 5 年,對我來說這些股票都是有生命的,甚至會覺得這些股票每天都會跟我說話,它如果狀況不好我一定看的出來。今天跌了 0.5 元對別人意義可能不大,但是對我來說卻是非同小可,可能就代表一個千載難逢的買點。現在的投資人太博愛了,每支股票都想看,哪支漲看哪支,這樣是絕對無法獲利的。
如同一個醫生不可能什麼疾病都會看, 一定有其專精的項目 ;只做專精的相關部份, 其他則轉往其它的醫師, 才能為病患的健康做最好的把關 .

immediate implant

A case of young adult female p't complained about " uneven incisal edge of ant. false tooth"
Via X-ray examination,we found the perforation site over the middle third of the canal . So we suggest ext. it and place implant and temporay restoration for esthetic consideration .


A Randomized controlled clinical study tell us about the effect of flapless implant surgery on soft tissue profile : Twenty-four patients with a missing tooth in the premaxillary region were randomly assigned to one of two groups(12 each): immediate loading (IL) or delayed loading (DL) (loadingafter 4 months). No significant differenceswere detected between groups at each time and over time inthe other clinical parameters, PD, mBI, mPI, and WKM (P >0.05).
Conclusions: The results of this study indicate that creeping attachment(i.e., soft tissue recovery) might occur within 2 months after IL. The study suggests that flapless implant surgery providesesthetic soft tissue results in single-tooth implants either immediately or delayed loaded. J Periodontol 2006;77:874-882
